The bomb spent 15 minutes loudly telling people to evacuate with an automated broadcast before it exploded.
So no, it wasn't a random Meth Lab explosion.
And, like, most bombings in the US (for example, the Boston Bombing, and the Oklahoma City Bombing) it was probably Political.
Also, please don't joke about Meth Lab explosions. One of those killed the wife of a good friend of mine.
So... they were at a baby shower for a friend of theirs', and the neighbor's house exploded. And my friend's wife was the only person who died, she took a roughly 95MPH pressure vessel to the upper torso. It had to be a closed casket funeral, it utterly pulverized everything above her heart. It's... It fucking sucks. Now he's a widower with 2 small children to raise. Happened just two years ago now.
At least it was roughly instantaneous. She probably didn't have enough time to feel pain.
And, you know, at least she's Christian, so she's probably going to be OK up in heaven.... I'm sad. That's enough internet for today.
