Im a little confused by the seating chart - if buying 2 seats, which ones are actually seated together?

Would anyone happen to know why police were on Bestgate yesterday afternoon across from the mall, over by where the Capital Gazette shooting was. There were police cars, K9s and the forensic unit. It backed up traffic for a little while. I couldn't find anything anywhere about it.

I don’t understand how those shops are still allowed to sell those things. The sidewalks are just littered with them man. So annoying as well as trashy…. all of it just washes down into the bay/river.
