what im getting at kharma, is that although the cop is a skilled driver,
the looney with the knife was not skilled at being hit by one. as a previous poster stated, he could have easily tripped, being in such a panicked rush, and become road pizza.
if they were willing to put him at such risk, they may as well have taken their chances with the taser.
it just made little sense to me since the cop only knocked him over the hood, which im sure he planned to do. and look at the results. the guy got back up without a scratch. at that moment, they failed.
the only reason they finally took him down was because he hesitated. he had plenty of opportunity to kill himself at that moment
