Maybe Howard Brookins Jr. will think twice before he criticizes squirrels again. Brookins had no idea just how “Aggressive” squirrels could be. On Nov. 13, the alderman found himself in the hospital with a skull fracture after a squirrel leapt into the path of Brookins’ bike, wrapping itself in the spokes and causing him to flip over the handlebars, The Star Tribune reports. Like the Chicago Sun Times, covered the incident but simply referred to it as a “Freak accident,” apparently afraid to call radical squirrel terrorism by name. The alderman has made the image his Facebook cover photo, as if to serve as a warning for squirrels who may try the same thing.
