I'd be interested in analyzing ATC transcripts to quantify the frequency of communication errors like that in day-to-day operations. Express permission, followed by an explicit (and matching) read-back, to enter a runway should be easy to identify (and the opposite as well). I see liveatc.net has audio archives, and tailstrike.com has transcripts of select accidents.
