Grandpa got put out of the meeting

People passing by a great auditorium noticed an elderly man being escorted out of the building by security personnel. Two minutes later, his family members exited the building. A passer by asked a young girl in the family about the reason for all of this commotion. She replied, "We went to a community meeting in there. Supposedly, we were suppose to address the crime problem. The panel guests consisted of a police chief, a politician, a celebrity preacher, and a wealthy businessman. The question was asked by someone in the auditorium what they were doing about these concerns. The preacher and his first lady replied, 'In order for us to do anything, you the public must first identify who causes these evils.' Well, my granddad stood up and requested that each of the panel members be given a mirror."
