Situation#1, come on man, noodle it through. If you are told to get on the ground and you don't, what do you think will happen. The officer will probably shoot you, so being dead and being right is not much of a victory, always comply at the scene. You can take up the officer's illegal actions at a later date. I'll never understand people that want to argue that they are not 'doing anything' when a cop is drawn down on them. Comply and sort it out after his weapon is back in the holster.
Situation#2, All of the above, to far out to speculate.imo
