Did you read what I said?
She probably would have bruised if he just cuffed her up anyway. She was resisting and if she fell, what are the odds of a broken hip, etc?
He gave her numerous chances to gain control of herself and comply. She refused every one of them and even DARED him to tase her.
He wasn't punishing her, he was trying to control the situation. She wandered towards the road during the full scene, she refused to sign the ticket, etc.
Should he have just let her drive away, thumbing her nose at the law?
Should he have tackled her? Ensuring she would probably suffer a broken bone when his weight came down on her?
I'm not saying his tasing her was done in punishment.
However, it's likely that's going to be the only consequence of this due to the inability of many folks to see past her advanced years.
They don't see the non-compliant person dropping the f-bomb and refusing to comply with reasonable and lawful requests. They see nothing more than the number that signifies her age.
If she was 27 instead of 72, we wouldn't be having this conversation.
Why should it matter that she was 72? You don't comply with a legal order, and continue to resist, the officer needs to use the most appropriate means.
Given her age, and how fragile folks think she is, it seems there are NO GOOD CHOICES.
Any choice, short of just letting her go, is likely to end up in her being injured. Just wearing the cuffs would probably bruise her. Even if she cooperated with wearing them.
It's a no-win, regardless the means used by the officer.
