... Washington State's extremely foolish policy of banning car chases of most suspects above the speed limit. As you might imagine, it has had some unintended consequences. The policy, which has only very limited exceptions where car chases are permitted, has caused a surge in auto thefts. More than a thousand people have evaded state troopers this year by simply driving a few miles per hour above the speed limit and refusing to pull over."
And in Chicago: "Chicago is now banning its police from chasing suspects on foot in most cases. The exceptions, once again, are limited. Police can chase those who are caught in the act of committing felonies or Class A misdemeanors, or about to commit felonies, or who are endangering the public (for example, by driving drunk, although this would presumably not apply in the case of a foot chase)."
