Re: [serious and organised crime]?
Serious crime - guy bashes in another guys head for ... reasons.
Organised crime - group of local thieves robbing houses as a team.
Serious and organised crime - group of thieves break into houses, beat the living snot out of everyone there, steal everything and then demand regular payments to prevent them from coming by and doing it all over again next week...
I think i see a difference... maybe... ;)
