Boston City Councilor Ed Flynn posted on social media about the police officer who was assaulted, saying "It should never be acceptable to assault a police officer or any law enforcement official."
It should never be acceptable to assault a police officer or any law enforcement official. An assault on a police officer, law enforcement official or first responder must always be prosecuted! #bospoli

Sunday's parade drew hundreds of thousands of revelers to South Boston. Green, white and orange confetti -- the national colors of the Emerald Isle -- rained down along parts of the 3.5-mile route.

The parade, which dates to the turn of the 20th century, marks both St. Patrick’s Day and Evacuation Day, which commemorates the day in 1776 when British troops left Boston after a protracted siege during the Revolutionary War.
Parade-goer Alex Brough found people mostly behaved after violence and public intoxication marred last year 's festivities. Parade organizers moved up the start of the festivities and neighborhood leaders warned of " zero tolerance ” for rowdiness and shenanigans ahead of Sunday.
Before the parade, MBTA Transit Police posted a photo on social media showing a pile of clear garbage bags filled with confiscated booze, including gallon-sized jugs filled with green liquid.

The seized containers were "BORGs," the TikTok trend known as "blackout rage gallons," where college-aged students binge drink gallon jugs of alcohol, electrolytes, flavoring and water.
Boston police shared a similar post on Facebook later in the day.
“There is probably a lot of alcohol consumed today," Brough conceded. “We witnessed it, but I think still people were overall behaving rather well, considered.”
