What is the difference between the officer shooting indiscriminately through a tin trailer killing a 6 yo boy and a gang thug involved in a drive by hitting a 3 yo girl in the head sitting in a Detroit living room.
NOTHING
cops generally - not always - are trying to do the right thing, the thugs never are.
the cops have sovereign immunity, the thugs dont.
courts regard cop testimony far higher than citizen testimony. even when proven later to be lying.
