Give them a toy and they will have to play with it. The problem is that you put a toy like this on the streets and there are apt to be a lot of men and women suffering from PTSD and if they see it on the street in an unguarded moment there is no tellling what they will do.
Another conclusion is that the government of the people and for the people could be preparing to become an entity of its own and the people become the puppets of the government. Dose not have to be a conspiracy but it will become more like a confluent of interests. You know, 1984 revisited.
Then again and not to be lost in the shuffle is that the cartel’s of Latin America have become so strong on our streets that the police need to purchase weapons of this nature not so much to establish law and order but for their own safety.
In the end, who knows but the point to bear in mind is that the militarization of the police is a very bad precedent. Police are trained to shoot (and wound if possible) only as a last resort to save a life. Soldiers are trained to shoot first and to kill. There is no middle ground in this equation. There is a second part of the equation and that is once you let loose with automatic weapons there is no telling where the bullets will end up. There are some heavy duty machine guns whose bullets will go through several walls prior to stopping. I have seen what a 50 cal will do to a human and keep on trucken for the next target.
