Cops Gone Wild! Shootings Across the Country

I commented on these three incidents in a guns discussion forum and took the position that the cops acted irresponsibly and were out of control in all three instances. I was surprised by the negative reactions to my posts.
In the New York incident cops fired 52 rounds, supposedly because one of them "thought he saw a gun". No gun was found.
In the south Florida incident 110 rounds were fired. This, of course, required reloading of semi-automatic pistols several times.
In the Atlanta shooting the cops supposedly had a warrant, announced their presence and then knocked the door down. The old lady was shot 9 times.
I don't expect that these departments will change their policies, but they should.
