Yes I am well versed in criminal law, my point I made was that if you have intel on illegal activities then it is best left to a LEO, especially in the forest, or as you put it near ball fields and such. Clearly whomever is doing that is a very sick person with no regard for public safety and sure not your life when you go messing with their traps. Being 6´3" in my book just means you an average size person, and if you feel your small size and personal look would help deter an armed criminal in the forest then I really hope you do not run into these armed people you speak of, because just in case your size is large where you come from then that person with the gun may take you as a threat in more ways than one.
Size does not mean crap, I am 6´6" at 275 with less than 5% body fat and I still get shot at once every 5 weeks or so, been shot several times, stabbed and blown up. Guess what it hurts and the perps really did not care at all about my size, they just wanted to make sure they did not go to jail.
On the other hand, assuming you are from the State you have listed on your profile I just logged into DOJ to check sub-agency data bases for rewards in such a matter. Your State list a 500 dollar reward for information leading to the arrest of such perps and 2200 bucks if they secure a conviction. Your States F&G also has a very nice budget in place supporting their wonderful SV Program. So to me that means it is 500 bucks money in the bank. Conviction rate sucks though, but still slightly higher than the national average, but I still would not count on that 2200 dollar reward with F&G convictions unless they are able to spin it under conspiracy, but then the perp would need to be very poor and very dumb, combined with an even dumber appointed attorney.
If it where me I would take the cash over the bullet any day, no matter your size bullets tend to screw up ones day real fast.
