Dearborn Police policies may well be used as a model for departments statewide. But, within safe parameters, police must chase the bad guys. Those who would do mischief in local communities already know officers are hesitant to pursue them beyond the city limits. Armed with that knowledge, some figure all they have to do is to make a break for the border and they're home free. At whatever point police can't chase the bad guys, it's open season for the criminals.
Any pursuit puts innocent people in danger.
When a cop says stop, it should mean stop, or you go to jail. There ought to be a law. So I'll try to make one. Your input would be appreciated.
