Poorly trained security officials aren't interested in or even have the capacity to come up with such accusations. Plenty of foreigners working legally might have 2 or more laptops with them.
Never even heard of immigration questioning someone based on what they're bringing into the country. Obviously, that's the job of customs, but they're mostly interested in ensuring you aren't violating customs regulations..
Each government department only does whatever their job role states. Therefore, I can't imagine a security official doing or saying anything unless of course you're attempting to smuggle something illegal. Then they'll call in the police.
