Well i used to work in law enforcement in Pittsburgh and we didn't have many hawks. I would've let you slide in this matter but but the DNR generally is stricter and more severe on punishment for offenses towards animals than we were on offenses towards other human beings. Personally if it happened on my property, that hawk would be blown to pieces. If you kept it quite and you were just protecting your lively hood it shouldn't be a big deal. well these are those government created jobs, they gotta give someone something to do.
