I'm not calling you dumb for having an opinion that is different than mine. However, you are forming those opinions based on either poor knowledge or flawed assumptions about the National Guard, it's training, and it's missions.
SWAT type engagements, where armored vehicles are most used by law enforcement, have very little similarity to actions in contact that the National Guard is trained in. While the Guard does train (rarely, and only certain units when necessary) on crowd control, training them in "arrest tactics", which would by necessity include training on evidence collection, civil rights, escalating use of force, etc. is far beyond the scope of the Guard.
Quite frankly, National Guard units have their hands full trying to train and maintain proficiency in their wartime tasks and mission set, especially in the face of the constant homeland missions they have had over the last 24 months. Any suggestion that they could do both flies in the face of reality.
Furthermore, I'd seriously question the thought processes of anyone who would bemoan the militarization of the police force, and in the next breath champion handing over police duties to the actual military. Soldiers are trained to close with, engage and destroy the enemy through overwhelming force. It's definitely not the mindset that should be policing our communities.
Several posters on here have tried to explain why policing with the military is a bad idea. Your continued refusal to accept the knowledge and experience of others makes me think that the only echo chamber around here is the one between your ears.
