[4] According to charging documents obtained by the media, initial gunshots from one weapon led to other people in the area to begin shooting over a span of 10 minutes.

Safe Streets workers also did not inform police of their activities as they are trained not to involve law enforcement in their interventions to maintain community credibility.

[23][24] In November 2023, the families of shooting victims, including those of Fagbemi and Gonzalez, said they were planning to sue the city and state over the incident, seeking a combined $150 million in damages.

[25] The families will be represented in the lawsuit by civil rights attorney Billy Murphy Jr.[26] Vigils were held in the Brooklyn community following the shooting.

[30] In November 2024, city officials held a press conference to celebrate achieving over a year without a homicide within the Brooklyn neighborhood.

[44] On August 31, police arrested 18-year-old Aaron Brown on numerous assault, gun, and attempted murder charges, and a minor, in connection to the shooting.

[49] In the morning following the shooting, Maryland Governor Wes Moore and several other Baltimore leaders released statements expressing their condolences.

[3][51][52] Baltimore Mayor Brandon Scott also called for further crackdowns on illegal guns coming in from other states[53][54] and criticized people who uploaded videos of the incident to social media for not intervening.

[58] Moore met with Brooklyn community leaders and people injured by the shooting on July 4, and later spoke at the Cherry Hill Festival to support gun violence prevention efforts in the city.

[62] Scott defended the role of the police as well as the city's Safe Streets gun violence program, saying the focus should "instead be on a few people who cowardly decided to shoot up a big block party celebration for a community".

[63] Worley blamed the lack of police for the event being "unpermitted"[64] and later said that decisions on whether to send more officers to the neighborhood for the festival happened "too late".

[68] Janet Abrahams, the CEO of the city Housing Authority, said that staff did not see flyers for the party that were circulating in the neighborhood and that officials would be expanding its contracted security force to additional properties, including Brooklyn Homes.

[16] Abrahams also said that officials were exploring evictions for tenants who organized the party without notifying the Housing Authority in advance, which violated the terms of their residency agreements.

MONSE interim executive director Stefanie Mavronis defended the city's youth curfew and the role of Safe Streets and its workers leading up to the shooting, pointing to the successes made through the agency's de-escalation strategy in parts of Baltimore, but said that she had not yet reviewed workers' logs about their efforts in the Brooklyn Homes area the night of the shooting.

[74] The Baltimore City Council held a second hearing on the Brooklyn Day shooting on September 13, 2023, following the release of the after-action report.

[82][83] In October 2023, Safe Streets modified its escalation protocol to require staffers to share details about large community events with the city, especially if the events have the potential for "mass harm or destruction", so that MONSE officials can increase violence intervention resources and potentially police presence at future gatherings.

[84] During the 2024 legislative session, Governor Moore introduced the ENOUGH Act, a bill to provide $15 million in grants toward underserved communities.
