Just to make it clear from the start, Cleveland police are saying they don’t believe that a mystery illness that has sent at least two troopers to the hospital for examination is related to stickers — which raises the obvious question, “What stickers?”

Here’s hoping it’s something innocent, although word is spreading that police have tracked down a protester slapping yellow stickers on cops that leave a tingling sensation when removed. Without meaning to spread rumors or cause any unwarranted panic, it’s safe to say that police (and the FBI) are aware of the incidents and are very interested to know more.

Tip: Do not slap stickers on police officers.
