I agree with Buckmine. He gave an intellegent answer that was indeed, very workable.
Recording evidence on cam corder is real good, too.

But grabbing a firearm, confronting these folks and playing sheriff ain't a good idea. No matter what the reason, if you pop some guy, or get popped yourself in a gunfight I will guarantee that you will regret it for the REST OF YOUR LIFE! You will face some serious charges, some serious lawyer fees, probobly some REAL prison (not jail) time, plenty of family hardships, both financially and socially plus a lifetime criminal record. If your or someone else's life isn't in immediate danger you'd be pretty hardpressed to convince a judge or jury that you were acting in a reasonable fashion by grabbing a firearm and proceeding TO the trouble. That makes you an instigator and aggressor. Prosecutor will TEAR YOU UP in court!

Think (with your upper brain) before you post. I understand your feelings and frustration, I will continue to do all I can to put poachers out of business in my areas and I think everyone should - but you got to keep it real.
