Given the needle in a haystack effect? Common sense has proven itself wrong repeatedly
It was "common sense" that merchants had to be frauds because the value of goods was universal and they had transport labor.
Besides just because they can doesn't mean they will. Authoritarians are also infamous for both corruption and finding rooting out dissidents a higher priority than what most would call actual crime. All other things /aren't/ equal.
Common sense is an useful tool. It helps us estimate outcomes when data is absent or scarce, even if it's frequently unreliable. When I leave my desk to go to the bathroom yet again, I expect it to be there. Can't prove it, but it's a reasonable assumption. Without it, every human action would require scientific studies and high quality measurements.
The way to contest common sense isn't to point out that common sense is often wrong; instead, it's to provide data. My assertion is that when going against a statement strongly rooted in common sense and, YOU are the one who has the burden of proof.
Yes, perhaps authoritarians would do a worse job at catching criminals if they were omniscient? I'm not saying that you ARE wrong, just that you are LIKELY wrong and thus you should provide data to support your claims.
You're correct. Authoritarians are also infamous for idleness and piss-poor execution of their duties (as well as corruption), as their are accountable to the power hierarchy above them but not necessarily the citizens. Thus, the motivation to protect citizens from crime becomes a second-order task - the real task is to stay in good with the authoritarian state.
