killer sniffer dogs at the big day out

i've just heard on JJJ that a greens senator in the eastern states has said that police are putting the lives of young people at risk by using sniffer dogs at the big day out. now this naturally caused my ears to prick up as i'm heading to the perth BDO in a couple of weeks and i certainly don't want my life put at risk so i thought i should find out more. how exactly are they putting people at risk i wondered? are the normally placid sniffer dogs suddenly turning rabid and tearing people apart? are their fleas spreading a new bubonic plague? are they causing an outbreak of mad dog disease? well... just wait for this... this greens senator reckons they're putting people at risk because if there's sniffer dogs there then people may take all of their drugs in one hit rather than spacing them out during the day. WHAT??? now unless i've misunderstood her and she's actually of the belief that the dogs are planning on forcing pills down people's throats then i can't see how it's the dogs that are putting people at risk. surely it's their own actions in voluntarily taking illegal drugs that's putting their lives at risk.. or have i missed some crucial point here?
