A veteran Philadelphia Fire Department battalion chief has been  accused of "conduct unbecoming' by the fire commissioner. The charges against John Grillone stem from a video posted to YouTube that firefighter Charles Tizol shot inside the quarters of Engine 71 on Cottman Avenue in 2009. Tizol has already been suspended without pay for four weeks and Chief Grillone had a disciplinary hearing yesterday.

So what is so bad about the video? According to KYW-TV the video shows Chief Grillone singing one of his favorite songs, the National Anthem and interacting with the firefighters. Here's more:

Grillone, a 38-year veteran, is seen singing, eating cookies and talking to co-workers in the video. There was some foul language used as well, but Grillone’s attorney, Alice Ballard, maintains the men were just simply having good clean fun.

Grillone says at the time, he was just trying to boost morale after the deaths of three firefighters.

The disciplinary hearing panel will make a recommendation to the commissioner in the coming days. A spokesman from the commissioner’s office said the fire department has no comment. As of right now, the fire department doesn’t have a social media posting policy in place.
