The town is incredibly safe, with an impressive police presence. Pedestrians entering Brookline for the first time from some of rowdier sections of Boston that border the town often speak of a noticeable change in atmosphere; there are fewer drunks and homeless people, more police, and the beer cans and cigarette butts that line the sidewalks of neighborhoods like Allston disappear. The town works very hard to keep it this way and police can be aggressive. Police in Brookline will often annoy the local high school and college populations for "rowdiness."
