A neighbor has shot and killed one cat w/ a gun and shot and injured another w/ a BB gun. Our backyards border an open field where the cats like to hunt. All adjoining neighbors are upset and concerned because this is a former juvenile delinquent with a history and no job, at home all day w/ mom and dad at work and doing this to show off to friends. We would like to set up a surveillance camera pointing pointing to their backyard (they have no fence) so we can have proof for law enforcement that he is the one doing this. Otherwise, they will do nothing, it’s perfectly legal to shoot a gun in a subdivision as long as you don’t shoot towards the road or into someones yard. Is this legal and can I use the evidence in court , if necessary?
