I think its very bad. These things shouldn't be a legal issue. Picking your nose is not nice. But we don't want to see police arresting people for picking their nose. You get the idea.
Jaywalking occurs when a pedestrian crosses a roadway where regulations do not permit doing so.
It is a minor crime at best. And before they actively go after J-walkers they should be working on the more important ones like drug dealers, murderers, speeder, and drunk drivers.
J-walking is an act in which people put themselves in danger, a topic which a lot of people think the government should not interfere with. But when they endanger themselves in traffic they are also endangering others people, specifically those in vehicles. Damages in a collisions are never one sided and a person being reckless with their own life should still be responsible for the damages they cost to other people's bodies or property. One of there very fundamental elements of law is to protect people from bodily or property damages and so I think j-walking laws should be enforced if, when they were legislated, they were deemed a reasonable enough measure of preventing traffic collisions. The only debate I feel is relevant is on a case by case basis when determining whether specific streets should have these laws or not, depending on visibility and other factors.
