To answer to original question, Would I have tased her? No, but like Rob, my dept. did not have a taser program. The choices available to me were ASP Baton, OC, or hands-on. I probably would have just went hands on, but it all depends on department policy.
The claims that the officer assaulted her when he pushed her back or that there was no need to get her out of the truck for a speeding ticket really depend on the rule of law in that particular jurisdiction. At my old agency and according to State Law, every traffic stop was a custodial arrest, but that if the subject would sign the summons (a promise to appear in court [if need be], or pay the fine) then, they would be released on their signature. If the subject refused to sign the summons, in essence, refusing to appear in court or pay the fine, then they must be brought before the Magistrate Judge to handle the matter in person. Of course 99% would sign the summons. I had several occasions where I needed to take some additional time with the subject to fully explain the repercussions of not signing the summons, but most realized that signing was a far better thing to do. Then you'd have the 1% that had to do things the hard way and they got cuffed, their vehicle towed, and transported to the Magistrate.
If this officer worked in such a jurisdiction and if the granny refused to sign the summons, then the LEO would be required to arrest her. At that point, any amount of reasonable force is sanctioned to effect the arrest. Now department policy on the amount and type of force would start apply.
As for the shove, after having worked in a large urban area where more LEO's were killed by passing traffic than by violent offenders, I would have physically moved her over to the shoulder or started walking over that way hoping she would follow me. If not, then yes, I would snatch her and drag her over away from traffic. At the time of the shove the LEO seemed trapped by the corner of the truck and the passing traffic.
In the end, this really is a public-image, no win situation for the LEO. Any amount of force used on a 72 yr old granny is going to tug at the emotional heart strings of anyone watching the video. This is one of those few instances where you have a job to do and laws to enforce. Sometimes people make you do things you don't want to do (like jacking-up a 72 yr. old grandmother), but that is the nature of the work. As others have stated, I would have handled it differently, but assuming the LEO followed the laws of his jurisdiction and his department policy on use of force, then he's justifed in what he did.
