i hate to say it, but im kind of on his side!
she WAS speeding, and needs a ticket
she wouldnt move away from the road when she was ASKED (for her own safety)
when he tried to move her physically away from the road (again for her own safety) she refused.
he tried to cuff her (not sure how he failed on this one, i think that would have done it myself) but failed.
so she gets tazed!
tough titties beligerent old hag! (no pun intended)
fighting her to forcefully cuff her risks breaking her bones, which will not be as tough as a 30yr old hillbillies.
a tazer will just drop her without damaging her (assuming her heart can hack it)
