Some of these cops are so illiterate and prosecutorialy-politicaly correct one-sided about the cases they are even sent for, it is scary. The constitution? Ah! Try have them do their job and provide you an accurate situational awareness of the case... then maybe we can start talking about testing them on the constitution.
Cops, in the US and like everywhere else seem to be trained to be idiots at times.
I don't know about training in idiocy. While it is true many idiots are hired as cops, they are not trained to be idiots. They are usually trained to be hard-a$$ed, and with some justification. You don't want a wuss dealing with criminals. Unfortunately, the many idiots hired at the fed, state and local levels of policing can't discern between normal people and the criminal element. They view us ALL as the enemy.
Idiot + harda$$ training = a$$hole training.
