The 2011 annual Wheeler Block Party at Western Illinois University (WIU) was met with brute force this year as a "multi-jurisdictional task force" was sent in to intimidate students with long-range acoustic device (LRAD) sound weapons, tear gas, riot gear, dogs, and even physical assaults -- all for no apparent reason.
According to a recent report from RTR.org's Reality Report, the annual WIU celebration was relatively peaceful throughout most of the day, with police officers present to maintain order as they normally would. But things turned ugly when those officers mysteriously left the scene for 30 minutes, leaving only a few officers behind who allegedly began allowing some rowdy students to "get out of hand" without intervening. Not long after, swarms of armed officers from various agencies arrived on the scene with military-style weaponry and gear, and began openly using it on everyone present at the event.
