Drill is normalising a negative and dangerous lifestyle. It isn't just local to the UK either and is fast becoming aspirational to a section of the youth. Much the same way as hard-core gangster rap did to the American impoverished population 30-40 odd years ago.
Educating your kids and promoting nuclear families will be the only way to keep the culture to a minimum.
But uncontrolled upbringings combined with poverished areas will always breed criminal and violent behaviour.
Drill is not the cause, but it does appear to be a catalyst.
Far too much common sense. Give your head a wobble.
