I don't get it...
Some people who live in the affected areas have lost their homes, whilst other people have had their employment affected through burnt out retail premises.
Surely what ever the difficulties of the area, this is not going to help people who live in those communities, you've just added to the misery.
This is just completely damaging the infrastructure of the area, anything from the buses that are damaged and burnt out, used by elderly people to get about and some people who are less fortunate to be able to have their own vehicle, through to the damage of emergency service vehicles that may be required to save someone's life. How's it going to help the area if local businesses have to shut up shop.
Hopefully when these people are brought to justice, we will be able to establish whether they were suffering genuine hardships and grievances or whether they were just pure home grown thugs, of the social system today.
