Does it give far-left users' data to LE as well?

Presumably only if they make violent and terroristic threats like the right-wing subjects of the article did. The valence of their political beliefs is irrelevant, making the headline highly misleading.

The question is not what Google presumably does but what they actually do.

What they actually do is give data to law enforcement when users make violent and terroristic threats, which is what the right-wing users described in the article did. I know this because I read the article.

Reading the article is usually a great way to find out what the article says, and I recommend it to anyone who is interested in knowing what they’re talking about before they open their mouth to opine.

Fun fact: when Trump was elected, Google's CFO, Ruth Porat, cried on stage during their weekly company meeting. I'll let you determine yourself whether there might be a bit of a bias in investigating left wing violent extremism.

Click-bait title.

The strong correlation between right-wing extremists and individuals threatening violence and terroristic activity means reports of the latter often mention the former.

This is akin to the observation that reality has a leftward bias, when interpreted by US standards.

Now, if only those responsible to act on the reports did not agree with the extremists...

ah, is that your position with blacks and "overpolicing" as well? that it's ok to treat certain groups specially when they're disproportionately violent?

Out in force, I see.

Reporting threats of violence disproportionately affects people who threaten violence, and coddles literally everyone who does not. You would change that, how?
