An update: The guy isn't likely to face any charges.
Police spokeswoman Tammy Ewin said it was unlikely the man would be arrested. The only charge likely to stem from the incident could be a citation if it were determined he fired the gun illegally inside the city limits, Ms. Ewin said.
Chief Dominic J. Costa, who was Downtown along with Mayor Bob O'Connor and other top local officials, said merely carrying a pellet rifle Downtown might not be against the law. However, he added, it flew in the face of common sense.
