Publicly disclosing the location of LEO's = "interfering"?
Discussion
I would say so in this case, its purposely telling those who would be arrested or have broken the law, not to go there. Which therefor inhibits enforcement. Look at is as the reverse of the registered sex offenders list. Which tells us where the bad guys are, very handy for parents. This app was telling the bad guys where the good guys are (i understand that of course is a matter of perspective)
Yes "bad guys" is very much subjective, I tend to side against the masked men ziptying pregnant women, but to each their own I guess...
And leaving aside for the moment the fact that "breaking the law" in this case constitutes predominantly administrative infractions related to immigration rather than anything that be considered a serious crime by most people...
Why should armed and (barely) self-identified LEOs have the presumptuous of privacy in public when members of the public don't?
