Yes it's clearly not a photo of the actual event. Are you complaining that you were misled? or are you suggesting "techbase" uses of stock photos is more authoritative than their own primary sources which I just summarized for you?
You said "I don't see anywhere people are saying it was actually SWAT" and I'm pointing you to where the article implies actual SWAT was involved, with their use of a photo of an actual SWAT team.
