Like many eastern states, New Jersey has very strong gun laws. People may even find themselves running afoul of weapons crimes even if they aren't aware that they are doing something against the law, such as collecting certain antique weapons. On other occasions, New Jersey residents might have an inkling that they are pushing up against legal boundaries with their activities involving weapons -- which is when it can be crucial to have an experienced criminal defense attorney fighting for your rights.
It's not unheard of for people in New Jersey to be arrested for one offense and then charged with an entirely different offense based on what police encounter. In some cases, that crime might be an even more serious one than what would have been charged initially.
