If you read the article, Lloyd grew up in Haiti and went to the US for college, which is where the two met. They then moved back to Haiti together. They're not some silly American couple with no business in Haiti, their family runs an orphanage and a school there.
Not really sure murdered missionaries trying to run an orphanage is a 'lol' situation.
The article also says that gangs are responsible for 2,500 deaths between January and March alone. There's no amount of knowledge that was going to keep these people safe. And the truth is, religion can lead to fool-hardiness quite quickly, and I say that as someone who was raised in the church. Their deaths are tragic, but also avoidable.
I wasn't so much talking about having the knowledge to make it safe as like actually having some business being there. It's certainly dangerous, just like it's dangerous for anyone who's living in proximity to that. But it's not like they're some idiot tourists, that's actually the life their family has focused on. Like, it's what they do.
