There's at least some states with hunting seasons (didn't try to do a comprehensive check). In general, city parks are not open to hunting, so hunting wouldn't necessarily help much with the geese that occupy them. I say necessarily because I can imagine a scenario where some particular flock of geese that spends time in a park also spends time on land that is open to hunting. Possible, but probably not that common.
