A tad of misinformation floating about with this one.
Edit for actual content
Firstly, these are both children - one is obviously a spoilt brat and has some HPA solenoid engine, but from the digging people did he's still in high school (15, actually). Other kid is young too, obviously. I say this only because of what I've put next and because of the assumptions people are making about his age because of his gear.
Secondly, the 'burning of the patch' - people have extrapolated this as meaning that other kid burned the shooter's actual patch. In actuality there's another video floating about of him (the guy that got shot) leaving the team they were both on and burning his own patch as a result. The shooter guy also cited some other disputes they'd been having over a year (as well as the 'patch burning' that is) as being the reason for shooting him.
All in all, it's dumb children sh*t that I've found to be telling of the UK airsoft scene on Facebook more than anything: People threatening to beat the living daylights out of this child or sending many, many abusive messages to him. The reactions have been less than impressive; instead of being level-headed players most people on social media have seen this as a frankly sad opportunity to form some sort of lynch mob and collectively give themselves some inflated sense of justice.
He's now banned from that site, the owner has also got involved after the publicity and will most likely issue a lifetime ban from that site and have other locals do the same as a result. This was assault and because of the publicity will probably trickle through to the parents via the police if they get involved, but from where I'm sitting it is - like I've said - more telling of some of the other hardmen we have knocking about who are more than happy to jump on a bandwagon that be sensible proactive players and commentators. Part of the reason I come on here I guess, because you guys aren't out to prove anything like some of those pretentious knob-heads - you just enjoy shooting and fiddling with toy guns and gear like I do.
Also, I hear this kind of thing isn't entirely unheard of at west coat sites. Lots of sites have banned HPA because of concerns over cheating, Joule creep and all the rest. You can already find three of four good fight videos where people forget they're playing with toy guns and have to turn it into something more. It's a reason why in the UK we need to be careful about using properly regulated CO2 (already banned in a lot of places because people buy cheap guns that shoot it far too hot) and that we keep ourselves in the know about Joule creep in particular.
The number of people running HPA rigs right now who don't know how to properly measure the output of their gat is pretty low, but as HPA becomes more accessible and people get more lazy about properly crono'ing their stuff I can see videos like this adding to the stigma that already surrounds some of the high RoF stuff. A cautionary tale indeed.
