My observation is that they go after easy targets who are no threat, not targets that are a real problem. So they’ll go after the upstanding citizen with an unregistered gun, not the dangerous thug with a stolen gun. The same way they’ll go after a little old lady who is going 10 mph over the speed limit, not a gang member who is dealing drugs.
The easy targets are a great source of revenue and no danger to anyone, least of all law enforcement. The gangbangers are a danger to everyone, especially an officer trying to arrest them.
Bad analogy
