1. The dumbest ones are most likely to be caught and have their stories told.
2. Law Enforcement often gets frustrated at chasing the smarter ones and use illegal methods catching them and the real story doesn’t come out in court.
I'm not saying this hasn't happened, but any competent criminal defense attorney (like a SMART criminal would have) would go to town on illegally obtained evidence. I'm not saying cops don't do warrantless searches/taps/etc., to gather unofficial clues, but if they can't get real evidence that stands up under scrutiny, the criminal walks.
I'm not sure if prosecution would move forward on such shaky ground in hard to prove cases.
I don't think 'going to town on illegally obtained evidence' works as often as you believe it does [0, 1].
And think back - how many people went to jail for national and/or international scale warrantless wiretapping? How did we, as a nation, respond to Snowden's revelations?

There are people on death row in the US even after being proven innocent and ordered to go free. Dignity in Ink [2] present similar cases every day - they're never going to run out of material.
0 - A major DOJ/GAO-era federal study found that illegal search/seizure issues accounted for about 0.4% of declined federal prosecutions and roughly 0.7% of dismissed cases after prosecution began. - https://www.ojp.gov/pdffiles1/Digitization/84544NCJRS.pdf
1 - Another study across seven jurisdictions found motions to suppress succeeded in under 1% of warrant cases, and only 1.5% of defendants went free because of successful suppression motions. - https://nij.ojp.gov/library/publications/search-warrants-mot...
His evasion and escape plan was actually pretty good and he put a lot of effort into being hard to trace by arriving and departing NYC via bus and staying in a hostel, which makes it surprising he screwed up the easiest and most obvious things.
and gives up, moving on to easier prey - and ideally getting them to plead to the other crimes I can't solve as part of a nice plea deal. Great for the stats.
