When you see the pictures of the armed robber of the store, you will see why he was pulled over. I don’t want to use the term “they all look alike”, but the pictures are pretty clear and he could be a double. Only a forensic person can identify completely, but it’s a match to me. The trick will be if the gun used in the robbery matches what was laying in his lap. It not a normal thug gun. Looks sorta like a Ruger .22 or something. Long skinny barrel with a Luger type grip.
I’ve studied the pictures and I could almost swear it’s him, that’s how close the resemblance is. One hitch might be the jawline whisker growth seen in the shooting aftermath video - not clearly present in the robbery still photo from 4 days prior - the question is whether 4 days would have been long enough to grow that much, and I think it’s very possible.
I’ve seen pics of the gun laying on the street next to Castile’s car from some distance after the incident, and it’s definitely not the same gun as seen in the robbery.
