One department in somewhere that I doubt anyone could find without Google Maps...and then the warning is picked up in a dozen places, more or less word for word. Maybe it isn't a bad idea since it is the first time that someone could doctor the date by just a couple of years...not a suspicious decade or two. However, if it was a serious threat I would hope to have heard it picked up by other, larger and more prominent police forces.
I just read the comment and thought it timely.
Having read a lot of documentary evidence of the past, to use the full date was definitely more normal in the days of real ink.
It's our prediliction for contraction that's the issue
