If you resist arrest... It DOESN'T MATTER if you have Dementia, or anything else. To resist arrest is to show disdain and/or disregard of those RESPONSIBLE to keep the peace. It doesn't MATTER if you weigh 80, or 400lbs. Once you present yourself in a combative manner YOU WILL BE TREATED accordingly. An 80lbs Grandma is just as capable of pulling a gun, or knife of a Cop as anyone else.
Sick up to my Goddamn ears with every armchair quarterback in the country second-guessing Cops.
