The last thing I'd want is for police to even need to tackle someone to the ground. That has too much of a possibility that it'll turn into a brawl. They need the ability to get the person to an incapacitated state as easily and safely as possible.If officers would lay off the damn donuts, maybe they could actually catch up to suspects and physically restrain them without the need to pull out their tasers or guns. This being America though, that's surely too much to ask for.
Unfortunately, tazers are the current best way to do that. Hopefully they'll come up with a better way in the future.
