If it were was a harmless event, such as being performed on friends, then yes. Some of this is hillarious. But any joy (or respect at their having 'a big pair') I could have gained from their actions has been mooted by the thoughtlessness of them. Ignore the risk they're putting themselves at, the ramifications of what they are doing could hurt a lot of people. Putting the risk to airsofting asside, they could have triggered heart attacks, damaged property and lively hood, scared people into emotional distress, gotten shot and caused another summer of rioting, gotten a member of the public arrested or shot by mistake.
I'm sorry to say, these people are just thick. And make me regret Darwinian evolution been put on hold.
