The restraint of UK LEOs amazes me. I saw on tv English police chase a motorcyle driving like a bat out of hell. The guy nearly killed himself several times as well as other people.
When he finally stopped the cops ran up to him and gave him "a talking to" and then a ticket. Here in America he would have been maced, beaten with club, cuffed then maced again.
I like the one with the spanish police giving in to a bank robber's demands. They gave him a fast motorcycle for his getaway, and he took off fast -- until they had a cop car shoot out of a side street right in front of him.
Newtonian physics can be extremely painful.
