Do you date people you meet randomly or do you have to know them a bit before?

It may sound like a stupid question, but I guess I’m always surprised at how people can see a stranger in public and go on a date with them right there and then, have that stranger in their house and their private life without knowing if they’re a criminal or something. Not only that, but they don’t even date for long, it’s like a fling. But I don’t mean it in a completely negative way, Perhaps it’s where I’m from and not every random person can be trusted. It’s great that In some parts of the world people can trust so easily.
But is there anyone here that absolutely cannot date someone they met randomly? I personally, have to at least be friends with them for a few months, get to know them a bit before I get them in my home lol, I enjoy group gatherings so my friends and his can mix and meddle. Once I gather that he’s a decent guy then I proceed to go out in a more intimate setting. How about you?
