The Illinois House has approved legislation that would impose tougher punishment on anyone convicted of using social media to plan or incite a mob attack.
Representative Christian Mitchell is a Democrat from Chicago. He says it's in response to recent incidents in which groups of young people use text messages or Twitter to organize attacks.
"I want to emphasize that thought he most famous issues with flash mobs have occurred on Michigan Avenue, this has happened in other places."
The legislation would allow a judge to impose an extended sentence if someone used electronic communication in a mob action.
The bill passed the Senate last month. The 102-to-6 House vote now sends the measure to Governor Pat Quinn.
