but as VictorKaum pointed out some legislations might try to show that a port scan is a certain warning for a future intrusion attempt.
That could be a bit of a "worrier". I scan computers quite regularly. Why? Because I want to know their "stance" as a result of suspicious activity from them in the first place. It is almost always an unsolicited contact on their behalf though I have had occasions where one of my workstations contacted them sometime recently and the activity followed either right away or soon after. I do it for a good reason. If the box shows me a bunch of open ports it's probably compromised. If I can then make some kind of connection, (anon ftp, wierd http etc.), then it goes straight on my blocked list.
