Ms Long praised the heroism of Constable Heidi Stevenson, who died while attempting to stop the gunman, but said she felt frustrated that the force held a procession for their fallen colleague in the days after the attack while "my family was still laying dead at their house".
She said the inquiry has made her lose faith in the RCMP.
She also accused the federal government of trying to politicise the tragedy to push gun control legislation - an accusation made earlier this year in notes by a local RCMP officer, which were released as part of the inquiry.
"The police don't always show up when you need them, especially in rural areas, so we must be able to protect ourselves," Ms Long said. "If Aaron had a gun that night, this tragedy would've stopped at his house."
