The London riots may have been the main topic on conversation on Twitter this week, but even they had a tech angle that got web users voicing their opinions. Here's our five favourite tweets of the week.

RIM to 'assist authorities' in catching rioters that used BBM

Twitter started the week buzzing with news and opinions about the riots that started in Tottenham at the weekend and quickly spread throughout the country. While Twitter was initially blamed for playing a part in helping gangs of rioters organise where to conrigate, BlackBerry ended up taking the brunt of the blame for its BlackBerry Messenger service. This lead to RIM confirming it would help the police in tracking down the culprits behind the riots and looting.
Deputy news editor CarrieSkinner said in a tweet: "RIM to assist authorities in tracking down thugs that used BBM to organise riots and looting".

Samsung ordered to stop selling Galaxy Tab 10.1 in Europe

It may have been impossible to ignore the tweets about the riots but there were some web users that were more concerned with technology issues. And one of the most talked about was Apple's victory in securing an injunction (if only temporary) in stopping Samsung selling the latest iteration of its tablet PC, the Galaxy Tab 10.1, in Europe. "Very bad news for Samsung Galaxy fans: 'Samsung ordered to stop selling Galaxy Tab 10.1 in Europe'," we tweeted.

Facebook to rival BBM with instant messaging program

BlackBerry's problems didn't stop at being blamed for its part in the riots either, this week. Facebook launched an app for Apple iPhones and handsets running Google Android that allows members of the social network to send messages to both their friends on Facebook and contacts in their smartphone's address book in a bid to rival BBM.
"Facebook throws down the gauntlet to BBM with their new smartphone messenger app," we said.

Thousands of tenants' unencrypted personal data and bank details left in pub

The Information Commissioner's Office (ICO) found two London housing bodies in breach of the Data Protection Act this week after a contractor left the personal data of thousands of tenants on an unencrypted memory stick in a pub.
Associate editor RosieHattersely  tweeted: "Lewisham tenants' unencrypted personal data and bank details left in pub."

London riots blamed on video games

It wasn't just BBM that came under fire for its part in the riots either. An unnamed policeman laid the blame for the London riots very firmly at the feet of violent, crime-related video games. He was quoted in the London Evening Standard as saying: "These are bad people who did this. Kids out of control. When I was young it was all Pacman and board games. Now they're playing Grand Theft Auto and want to live it for themselves."
Editor MattJEgan said in a tweet: "Intrigued to see that the best-read story on @PCAdvisor right now is the now traditional 'expert says riots are caused by video games'".
