Just before New Year's, the Nova Scotia Utility and Review board reinstated the liquor license of a popular bar in Halifax on the condition (among others) that the bar double the number of surveillance cameras and allow liquor inspectors and the cops to have offsite access to the feeds (see: Canadian Privacy Law Blog: Offsite surveillance in Halifax bar may set precedent and Canadian Privacy Law Blog: Halifax bar gets liquor license back on condition that cops have off-site access to surveillance system).
When this report came out, I voiced some concerns that this may set a dangerous precedent. Any move to implement such a scheme has to include very tight controls over how this new-found surveillance power will be used lest it be a license for unimpeded and unrestricted intrusiveness.
In case you were wondering what the slippery slope of function creep (to mix my metaphors) looks like, look no further than random ID checks in casinos in Illinois. Random identification checks by law enforcement officers were put in place to deal with excluded problem gamblers. Assurances were given that there would be no other use of that information or other abuse of this power. Now it's reported, shockingly, that the cops in Illinois casinos are checking for problem gablers, sex offenders, outstanding warrants and other micreants. See: Daily Herald Police admit ID checks in casinos turn up more than problem gamblers.
To put it bluntly, function creep is a very real phenomenon that needs to be anticipated and guarded against whenever a new intrusive technique or technology is rolled out.
