Listen kids, which most of you are, and know this well.
The law is the law. You do NOT get the liberty to pick and chose which laws you want to abide by because it manages to overlap with your hobbies. The laws passed and enforced are not biased or directed at any individual or group in question. Odds are the Police departments have no clue or even care who you all are. The people that set these laws into motion do NOT care you can not leave town or get to the appropriate area to shoot. Remember you are NOT 18 years of age and for the most part not seen as a contributing member of society(voting, taxes) so the only thing they care about is SAFETY. Not only the safety of yourselves but those around you. Other than your home(which is not even yours) you have no right to use or have ownership of ANYTHING. How long you have been playing or the level of safety you take DOES NOT MATTER if the use is illegal or the user. The sport you have chosen replicates WEAPONS all of which have been designed to KILL and nothing more. My P90, G36 and AUG are weapons of war designed to kill human beings, that is why they exist. Most people, including experienced airsofters, can not tell the difference between a Baretta M9 and a HFC M9 at 30 feet in DAY LIGHT. That is a very good reason why these types of laws are passed. Knowingly or not they SAVE your life or the life someone else. By Arizona statute(which I will not quote you look it up) it is a misdemeanor to even SHOOT a person with an airsoft gun and a FELONY depending on the situation and who you shoot. Even pointing the gun in the direction of someone that doesn't know what it is, is a FELONY. Also no waiver on EARTH can protect a person from killing or seriously wounding another insanely more so then a "innocent" kid.
Let's say that, as an example, the Forest Service owns the land that you wish to use and give no permission tough luck. You have no rights to use THEIR land that they upkeep. Trespassing is trespassing regardless of age or intentions(unless its lawful) and you are ALWAYS in the wrong. What would have happened if you or your friends you have been attacked by a mountain lion or bitten by a snake? Even though the Forest Service has already said no there is ALWAYS the chance they could get into trouble even more so if they did not know you were there. A dead kid or serious injury on their watch on their land will not sit well with them or the government. All because some people wanted to play a game and disregard what they were told making legal players suffer. Do you even know what will happen to the officer that kills a kid due to an airsoft gun all because he was doing his job or those Forest workers you just put in the cold not stopping they knew nothing about.
As said before, LIFE IS UNFAIR. It gets worse when you get older depending on the choices you make now. People do not forget comments, actions or first impressions. You get no seconds chances and your buddy WILL rat you out(stats show it). Tell your SOB story to the mother of my little brothers friend who died doing something that they should not have been at their age. I don't even think it was an open casket.
