Yeh for sure. Its also about society messages including the post commentary to come out of this kind of tragedy, if you keep telling a demographic of people that they are good for nothing and there is no hope, you get alot of that.
I have a good friend who does alot of social work in South London, one of the capitals of knife crime here and its the same thing there, these kids are not born to be killers with knives but the messages that surround them are negative from early on "you are black, your dads not around, you have not future, you will just be like him" that makes them easy prey for gangs. It goes a long way to forming the minds of the kids,
Not to go too deep and left field, I think the schools system needs reform for these hotspots, kids need attainment targets that apply to them, you know from an age kids who will thrive academically and those that don't have the aptitude or care for it so why not reform the system so that rather than French, Shakespeare and Science have a futures pathway which gets kids ready for life and work. Get kids to feel the rewards of what it means to earn and have money in their pockets, kids love rewarding and stuff thats attainable so have something that does that within their skills or desires. I don't think work experience or cheap as chips work schemes post school is enough. Yeh it would be long and it would be complex (it should be) but kids deserve more than being taught archaic subjects that won't have a bearing on their lives when they leave the class, thats if they even turn up
