The gunman has been identified as 27-year-old Daniel Giddings. Giddings was recently relased from prison for aggravated assault with a gun, and was wanted for assaulting four police officers after he was stopped for a traffic violation.
As tragic as this is, why the hell was this guy out of prison and free to walk the streets? This guy is a career scumbag who was released back into the wild. No doubt Mayor Nutter will use this as a linchpin to take away the rights of those who didn't do it by making it harder for them to own the tools that will protect their homes.
You cannot stop violent criminals at the cash register, and "enforcing the laws on the books" will do nothing to stop criminals. Keeping them locked up is what it takes.
