I don't think it's the alcohol that's the problem, or at least not in the way that the media would have us believe.
I spent quite a lot of my teenage years drunk with my mates. None of us ever beat anybody up, none of us ever stole anything, none of us ever disrespected anybody, none of us hung around the streets at night intimidating people, none of us damaged anybody else's property.
We just went out, scored some (cheap) booze, got drunk, and had a bit of fun. If it was raining we went indoors, if it was sunny we found somewhere quiet to sit and have a mess about.
We even through our cans and bottles in the bin when we were done
So, if (about 12-15 years ago - God, that makes me sound old) we could enjoy ourselves without maiming, abusing, or killing anybody, why can't 'the youth of today' (now I
really sound old!)?
