Also apparently I was partly wrong, this is from the wikipedia article about the shooting:
On the day of the attacks, authorities stated that four suspects were arrested.[105][106][107]
Two days after the attack, Police Commissioner Mike Bush stated that separate from the main suspect, the three other people arrested were not charged in relation to the attacks and did not appear to be involved in the attacks. Bush then gave the following descriptions of the other three suspects:[108] Police arrested a woman and a man after finding a firearm in a vehicle in which they were travelling together.[109] The woman was released uncharged while the man was held in custody, charged with a firearms offence.[110] An 18-year-old man was arrested after he armed himself with the intention to "assist children in the area"; he will appear in court on 18 March 2019.[60][111]
Additionally, a 30-year-old man claimed he was arrested when he arrived at Papanui High School to pick up his 13-year-old brother-in-law. He was wearing camouflage clothing, which he habitually wore.[112]

Tarrant was driving there when the stream cut off. Read the manifesto, he said he was attacking both mosques and he even had a third planned.

Bro this happened after both shootings when the police were chasing down/arresting Tarrant. Some dude sitting at home that heard the gunshots would definitely have time to throw on some fatigues and grab a gun to go play hero
