I might, as ex-LEO, quibble over some of the phrasing or certain details... but you're not entirely wrong.
I saw the change coming when I was in LE, and I didn't like it. Yes, there's always been a certain "Us vs Them" mentality, but it has grown beyond all reason. When I was a cop, I had a pair of cuffs, a radio, a pouch containing rubber gloves, two speed loaders, and one revolver on my belt. Today I see guys with two or three 15 round mags, Taser, pepperspray, two sets of cuffs, expanding baton, and more pouches with I dunno what in them. More and more, what we used to consider routine ops requiring two uniforms are today performs by 3-12 cops in tactical gear... of course, all of it black, armored and intimidating looking.
Apparently stuff I used to deal with solo, with my voice and authority as my primary tools (backed up by my hands and if need be my sidearm), now requires a heavy-weapons squad.
PDs are getting millions in Fed funding to buy all the tacti-kool SWAT and anti-terrorism gear and weapons and vehicles, then the dept feels obligated to USE the stuff to justify its purchase and maintenance... and you get situations where you have a platoon of cops looking like black-masked Storm Troopers on the street just to arrest a small time pot dealer.
That's not what I signed up for, and I'm glad I'm out, is all I'm saying.
