The Boston Bruins are in Vancouver to take on the Canucks, but Boston police are deploying hundreds of extra officers to patrol the streets around TD Garden and Fenway Park, neighborhoods with dozens of sports bars where fans congregate. State police and transit police are also beefing up their presence.
Raucous celebrations after big wins by the New England Patriots, Boston Red Sox and Boston Celtics in the past seven years have resulted in three deaths and widespread vandalism.
The city and police have learned from those tragedies, Boston police spokeswoman Elaine Driscoll said.
The city banned on-street parking in the same areas from 6 p.m. ET Wednesday to 2 a.m. ET Thursday and urged fans to use public transportation.
Bars are being asked to take in or secure outdoor furniture, black out windows to prevent crowds from gathering outside to watch the TVs inside, and not admit any customers after the end of the game's second period...
After consulting with police, the Bruins also decided against holding a viewing party for as many as 15,000 fans at TD Garden...
The article goes on to describe incidents leading to injuries and deaths following previous Boston championship victories during the prior decade.
