they assume they are free to ride on sidewalks, run red lights and stop signs, etc. etc. mostly because there is zero enforcement of these laws, too.
Are you talking about the car drivers too? I see everything except driving on sidewalks on a regular basis. I can't count the number of times - as a pedestrian - I've almost been hit by a car going through a red light, turning right on red and trying to drive through the people crossing the road with their signal, or running a stop sign, all of which seems to happen with zero enforcement of the law. And then when the city wants to put in red light cameras to stop people doing that, people scream about their constitutional rights. (*My* constitutional right to not get hit by the aforementioned idiots seems to go unnoticed.)
