Look, for all I know that horse was chock full of plastic explosives, though it sure didn’t look like it from the way it blew up. I imagine some paranoid parent saw the thing and called the cops, the cops had to respond, then they showed up and saw that it was obviously just a toy horse and the conversation went something like this:
“Dude, this is obviously just a toy horse.”
“Yeah, but we came all the way out here and we’ve already got all our bomb stuff out. So we should probably blow it up.”
“Obviously.”
And let the record show, that’s precisely the type of logic I’d employ all the time if I were a cop, because if you’ve got opportunities to blow stuff up while you’re on the clock, you take them.
Excuse me: Don’t look a gift horse in the mouth. Blow it to smithereens.

Ridiculous in every sense of the word. A toy, in a park, somehow trigger a person to think “bomb”?
I mean using that standard of paranoia, along with the protocal followed by the Orlando PD, makes me wish I lived in Orlando.
I’d be calling the cops about every random object I came across that looked even the slightest bit out of place figuring I could get a street locked down and see something get blown up.
Or, like, dude in a bar pisses you off, so you call the cops and tell them that his car looks suspicious. Voila, instant revenge!
