tasering is safer for the cop and arrestee.
The whole 200 lb cop tasering a poor girl argument is stupid. She has a much greater chance of being injured if the cop used brute force. A lot of people were killed by cops using choke holds, batons or just force of numbers before tasers became the norm. Another factor is that they made life safer for female police as well.
Tasers also give cops a non-lethal option that is appreciated by any black man who still is brave enough to carry a wallet.
In most of the cases where someone was legitimately tasered a gun or physical violence would have been the been the only other options. In the bad examples, and this is not one of them, the same security guards would have ended up using a higher degree of violence. Ask anyone, you're not going to get brilliant minds for what most companies have budgeted to pay security. Ths security guard being an off duty policeman increases the chance the tasering was justified.
Stop defending retards.
