"Mortimer" gurgled happily, sounding much like they were
saying:

I note that you were unable or unwilling to deal with the "first three
seconds of red" bit of the posting.

I didn't mention it because I was taking it as read that going through a
red light, even in the first three seconds, is an offence

Same as doing 71mph on the motorway is an offence - but not one that'll
be prosecuted. Zero tolerance doesn't work as a blanket policy.
