You would rather he humbly submit to an illegal arrest and search? I'd argue we need more men and women who are not afraid to stand up for themselves and to make it clear to our law enforcement that we will quietly submit to the usurpation of our rights. If you want to stand mute, by all means feel free to do so. I, however, would not.
Was it the officers intent from the outset to arrest the suspect?
Whats the phrase we often utter? An armed society is a polite society? Had Grisham been polite and respectful and simply put the rifle down, in all likelihood there would have been no arrest at all.
("Why couldnt you just put the bunny down?")
What evidence do you have to support your opinion that the responding officers were trying to usurp the suspects rights from the start?
