When is a killing justified by self-defense? My survey reveals that we’re not that sure.

We all think we know what “self-defense” means as a justification for killing someone. But based on my survey of 186 people, our perspectives are nowhere near consistent. Here’s a recap of the data you’re about to read about. Using my blog, my Twitter account, and my Facebook page, I encouraged people to take a…

Facebook is purging face recognition. Here’s why I don’t trust it.

For a decade, Facebook (now known as Meta) used facial recognition to tag millions of photos with the identities of the people in them.

Judge minces no words when sanctioning Trump lawyers Sidney Powell et al.

Federal judge Linda V. Parker had the task of determining if Trump election lawyers including Sidney Powell and Lin Wood should receive sanctions for misuse of the judiciary system in Michigan.
