Because dangerous people should not own guns.
Real simple concept. Wanna own guns, dont be a felon.
There is absolutely no connection between somebody who does time for investment fraud and the Second Amendment. Singling out ones Second Amendment rights for denial for a crime not associated with abuse of a firearm clearly shows either total illogic or a bias against Second Amendment rights when you clearly ignore all the other rights you could also deny the individual.
If a person committed a crime that did not involve the use of a gun, there is no logical reason to deny them their Second Amendment Constitutional rights in the future.
Why would you selectively and arbitrary pick on one Constitutional right - the right to keep and bear arms when their crime did not involve a gun?
And if you are okay with the denial of their Second Amendment rights, are you also all right with denial of other Constitutional rights. Lets go through them:
Would you also deny them the right to freedom of speech?
Would you also deny them their rights under freedom of the press?
Would you also deny them their rights under freedom of religion?
Would you also deny them their rights under freedom to assemble?
Would you also deny them their rights to petition for redress of grievances?
Would you also deny them their rights under the Third Amendment to keep their homes free from quartering of troops in peacetime?
Would also deny them their right to be safe from unreasonable searches and seizures?
Would you also deny them their rights to be not arrested unless on probably cause?
Would you also deny them their rights to not answer for a crime unless indicted?
Would you also deny them their right to be protected against double jeopardy?
Would you also deny them their right to be protected from self incrimination?
Would you also deny them right to thei own property from being seized by the government without fair compensation?
Would you also deny to them the right to a speedy and public trial by an impartial jury?
Would you also deny to them the right to confront witnesses against them?
Would you also deny to them the right to have counsel or an attorney in their defense?
Would you also deny them the right to sue in court ?
