Security in ARN, as well as OSL and CPH, all have flaws in that most checks can be circumvented if you know how. This is probably valid for most airports.

HIA has a list of airports that it regards as secure and arrivals from these airports are not normally required to go through security in DOH. But there are spot checks.
