social media on the affect of the riots

1) What effect do you think social media had on the spread of the summer riots? 
the social media, like Facebook and Twitter played a huge part to the spread of the summer riots, as it made communicating to a big number of people much more easier, gangs and all sorts of different social groups spoke about what was going to happen next and what they were planning to do on these widespread global sites, pages were made to encourage people, rumours were spread to keep the police and the public aware.
the social media played a big part to the expansion of the riots, and the copycat effects that were carried out. there alot of reasons as to why the riots were started and comprehended, but it would never had gotten as big as it did without the powerful source, the internet. If there hadn't been this media source the riots would have been kept to a much smaller state and the authorities would have much more sense in what they were doing.
Also a more covert social network was being used, the blackberry messenger, as it is not tracked and can not be seen publicly, this was an easy and more safer way for rioters to announce what was going to happen, alot of places were possible targets.
