That misses the point. Treating the police as not being your friends ignores the problem of Enforcement protocol and it ignores the problem of stupid old laws being enforced only when it is convenient.
Without a defined system in place to obsolete old laws at regular expiration dates, what is left in place is a system that forever stacks new laws onto old laws until the entire nation is mired in nothing but law after law such that everything becomes illegal eventually.
“Police are not your friend” is a general rule of thumb and, therefore, a general statement.
Selective enforcement along with a continuous legislative avalanche is a product of the vast administrative state. A “sunset clause” should be included into almost every piece of legislation and regulation. However, that’s a threat to those feeding at the trough and the masterminds.
