Isn't it obvious?  They're dressed for a drill.  Don't forget last summer, 2017, when London police were caught on June 3, 2018, changing outfits and posing as "terrorists".

6/3/2018 = 6+3+20+18 = 47
7/22/18 = 7+22+18 = 47

As another note, this shooting came on the day leaving 162-days left in the year, in an MLB city, and one of the plainclothes officers is wearing a Boston Red Sox hat.
