They are probably located in a country where it is easy to bribe the policemen, and factor that into their cashflow calculation.

It really depends on how much noise/attention they attract.

Bribing one policeman or a department, or a national level LE body, and so on?

Due to the nature of the internet and social media there is an ever decreasing chance of flying under the radar.

Even if a country's entire infrastructure is corrupt, you would still have to deal with a never ending list of 'beaks to wet'.

Bribing a LEO seems to be a risky business - how risky depends on the conditions. If you're the only one bribing an officer, you'd better ensure you have that consistent cashflow. It's easier if everyone is bribing the police. But still, the moment you interact with law enforcement, you appear on their radar. It's always better to avoid that unless absolutely necessary.

I disagree with this statement though. I think that Internet as it is now only makes it easier to fly under the radar - simply because people generate such a huge amount of noise that it's barely possible to handle. As long as you don't get too greedy, you can get away with a lot, simply because nobody is going to bother looking for you (hence e.g. spam).

I should clarify that while the simple existence of the Internet doesn't make getting caught more likely, social media at least increases the chance of someone on the related social graph seeing something, and reporting it.

That's actually a bigger risk.

If there's no police protection for the victims there's also little police protection for the criminal.

If I were a ransomware scammer I'd rather be caught and jailed than killed by irate victims or competing criminals.
