The title is completely sensationalized.

There was one person who disrupted it by shouting about Gaza (a worthy thing to shout about), and just shouting that she was a liar. AOC maintained her decorum; the crowd became irritated with the disruption, and booed the person, who was shortly thereafter escorted out. Not arrested - escorted out. AOC then followed this up with:

“Here’s the deal, with town halls: I more than welcome people who disagree or are maybe even super pissed off at me for any issue to come but we have some ground rules here. Please wait for the Q&A because we don’t want to deprive all of our neighbors of the ability to have information and hear things and respond to it,” Ocasio-Cortez told the crowd.”

I genuinely cannot think of how she could have handled this better or more gracefully.
