Near the end of the second day of closing arguments in the Google monopoly trial, US district judge Amit Mehta weighed whether sanctions were warranted over what the US Department of Justice described as Google's "routine, regular, and normal destruction" of evidence.

Google was accused of enacting a policy instructing employees to turn chat history off by default when discussing sensitive topics, including Google's revenue-sharing and mobile application distribution agreements. These agreements, the DOJ and state attorneys general argued, work to maintain Google's monopoly over search.

According to the DOJ, Google destroyed potentially hundreds of thousands of chat sessions not just during their investigation but also during litigation. Google only stopped the practice after the DOJ discovered the policy. DOJ's attorney Kenneth Dintzer told Mehta Friday that the DOJ believed the court should "conclude that communicating with history off shows anti-competitive intent to hide information because they knew they were violating antitrust law."

Halfway through the first day of closing arguments in the Department of Justice's big antitrust trial against Google, US District Judge Amit Mehta posed the question that likely many Google users have pondered over years of DOJ claims that Google's market dominance has harmed users.

"What should Google have done to remain outside the crosshairs of the DOJ?" Mehta asked plaintiffs halfway through the first of two full days of closing arguments.

According to the DOJ and state attorneys general suing, Google has diminished search quality everywhere online, primarily by locking rivals out of default positions on devices and in browsers. By paying billions for default placements that the government has argued allowed Google to hoard traffic and profits, Google allegedly made it nearly impossible for rivals to secure enough traffic to compete, ultimately decreasing competition and innovation in search by limiting the number of viable search engines in the market.
