Fair enough. Here are some questions I have regarding them, not knowing police procedures.
1. Agreed. I'm not sure how the location of the vehicle changes anything, but it should have been secured and searched.
2. From anything I've seen the only interaction Zimm had with witnesses was before the police arrived and everything said is in the record of witness statements.
3. As for the Ooster guy, him talking with a friend cop he knew at the scene after arriving MUCH later doesn't change anything and if the cop gave him his opinion based on what was known at the time, well that doesn't change anything either.
Zimm was immediately taken into custody and with the exception of being attended to by paramedics I haven't seen or read that he interacted with anyone but police after that. I believe he was then taken to the police station where photos were taken. Again, I don't know it if police procedure is to take such photos immediately at the scene, but considering the cop used his cell phone and wasn't equipped with proper camera equipment to do so i'm going to guess no. We also don't know when the evidence gathering team arrived, before or after Zimm was taken away.
4. The paramedics documented Zimms injuries and also noted he didn't seem to be suffering from any more serious injuries other then his nose and back of his head. I'm not sure if it's required to send someone to the hospital in this instance when they refuse. Also, was Zimm under arrest? I'm not sure if there is a difference to arrest and "taken into custody".
5. From my understanding of the reports, the police weren't aware of the sidewalk issue until Zimm made a statement later at the police station, maybe the next day during the walk through. I think the rain would have washed any evidence away.
Also note there is no indication any investigation was done for blood evidence anwhere else on the ground and considering TM was initially laying face down, there should have been blood on the grass.
Let me just make it short for lack of time. The location of Zimmerman's parked vehicle is very significant. Whether he was parked near the mail station by the club house as he initially indicated in his drawing to the female investigator and then quickly scratched it out or was he parked near the cut-thru as he indicated at the "re-enactment" video called into question of the timeline. If he was parked near the mail area by the club house, his excuse for getting out of the truck for an address become even more ridiculous because the clubhouse is just near the entrance by the main entry road. Also, he shouldn't be anywhere near the cut-thru let alone where Trayvon's body was found because when he got out of the truck and ran after Trayvon it was only a few seconds of running when the dispatcher asked him was he following Trayvon and he said yes. Off the top of my head, I remember it was somewhere between 17 to 20 seconds when the dispatcher said "we don't need you to do that" or to that effect and then he said "OK". No matter which direction Zimmerman ran or where he was after the run, he should be back in his truck within the 17 to 20 seconds time frame give or take 10 seconds for good measure and he would still be on the phone with the dispatcher while back sitting in his truck before the conversation ended. After hanging up the phone with the dispatcher he still had about two minutes sitting in his truck waiting for the police to arrive instead of pulling the trigger on Trayvon where the body was found.
Osterman not only talked with his buddy police officer but he also spoke with Zimmerman at the crime scene. I would not go over the rest of the other points as we clearly don't see eye to eye but I'd like to point out that blood stains on the concrete can be tested with luminol technique not just the next day but a few days or weeks later (Loy and Wood, (1989) were able to use the most basic test for blood commonly used in crime scene investigation and applied it on approximately 9000 year old archaeological evidence from Cayonu Tepesi in Turkey with successful result).
There was a murder case in West Memphis where investigators went to the murder crime scene a week after the murder to perform luminol test on the crime scene. The crime scene wasn't a nice solid concrete surface as in this case. It was located outdoor in a hilly wooded area and they were able to locate blood evidence with luminol test where the bodies were found, at the trail and bluff. This despite their report of "the weather conditions of some light rain the night before and the originally low concentration levels" found at the sites.
So, even if there was an attempt to wash the evidence away with water unless bleach was used, the presumptive test for blood is still possible. If someone had attempted to use bleach to destroy blood evidence, luminol would mask the blood stain evidence, thus requiring a different test for blood evidence.
Whether Zimmerman bled a lot or very little after being allegedly slammed into the concrete repeatedly for almost a minute, luminol could still detect trace amount of blood if present.

Luminol Chemiluminescence Test for Blood - How to Use Luminol to Test for Blood
The luminol solution is sprayed where blood might be found. The iron from the hemoglobin in the blood serves as a catalyst for the chemiluminescence reaction that causes luminol to glow, so a blue glow is produced when the solution is sprayed where there is blood. Only a tiny amount of iron is required to catalyze the reaction. <snip>
If a crime scene was washed in bleach, for example, the whole area would glow when sprayed with luminol, making it necessary to use a different test to find traces of blood
Luminol test has been in used by crime scene investigators for many decades. I'm sure the SPD would be well verse with it. They could have immediately went back to the crime scene that ver night after the interview or after the video "re-enactment" and test the specific spot where Zimmerman indicated his head was bashed. They should also test the whole concrete walkway starting from the T-junction all the way down where Trayvon's body was found. But, they just simply failed to perform it. Not just this but there were many other important thing they failed to do, such as checking into Trayvon's cell-phone instead of simply returning it to his parents.
What the SPD investigators eagerly failed to do in shirking their duty, they sure make them up with diligent haste in finding Zimmerman not guilty by reason of self-defense. Thus, they sure came out in droves and in a hurry from the top down to vouch for Zimmerman without missing a heart beat, to wit:
1. Osterman said he was told by his buddy police friend at the crime scene that the case is clean, meaning it was self-defense.
2 Singleton noted "that she was told beforehand by a fellow officer that the case "might be self-defense.'”
3. In the early weeks after the killing, Bill Lee stepped up onto the podium before the press, claiming, "All the physical evidence and testimony we have independent of what Mr. Zimmerman provides corroborates this claim to self-defense.”
