Someone took the CNN article, read it, and wrote an opinion piece that is grossly slanted. There are several parts that are factually untrue.
The stats I've seen argue otherwise. The quotes I've read from criminals state they are more worried about a potentially armed target, than they are the police.You are not going to stop a crime. If you do stop a crime, you will be an extreme outlier to a trend that overwhelmingly results in the death of innocents.
