You can’t give military style tools to poorly disciplined police forces without consequences. With the NSA or the Army, the problems are policy. With an org like NYPD, they don’t really have control of “the troops”, so who knows what’s happening.
This is correct. It's also the argument for ending qualified immunity and defunding the police.
These people may even benefit from over policing wrt kickbacks from private prisons. For example, Marco Rubio [0] is a top recipient of money from the private prison lobby, and he's run attack ads wrongfully saying that his political opponents want to abolish police, and he himself ran on a platform pushing for larger police budgets.
