Trespassing cop goes on couples property to demand ID, man tells him he owns property and orders cop off property, cop refuses to leave and puts man in cuffs. No reasonable articulable suspicion under the law, just a cop who thinks he's above our rights and law and demands that we answer to them while the cop criminally trespasses.
Armed trespassers refusing to leave the property and attempting to cuff the owner are a threat to the owner and citizens are justified in using necessary force to end that threat. Cops are not above the law, and they're not above the peoples right to defend themselves and their property.
