Let me get this straight. So instead of being greeted by a beautiful woman, you could get tackled by some 250 lbs. gorilla, get thrown in jail with Bubba for the night, be fined several hundred dollars, and be labelled as a sex offender for the rest of your life? Seems pretty sick to me.
The letter of the law states that prostitution is legal. However, pimping, soliciting in a public place, and being on or operating a bawdy house is illegal. A bawdy house is a place that has prostitution as its express purpose for existence, which is why all such places in Edmonton end-around this law by calling themselves massage parlours rather than brothels. Theoretically, from a legal standpoint (but maybe not a personal safety standpoint) an SP is safer operating outcall from her own place rather than renting out a separate location for incall, since the sole purpose of the residence is not prostitution but living.
The reality of the matter is that cops don't care, like Missy M says, as long as all parties (pooners and SPs) keep their noses clean otherwise. But the bawdy house card is one that the cops can and do play to bust MPs when there is say, human trafficking, prostitution of minors, etc.
What if you don't respond to an ad, but instead make one yourself, say in craigslists's casual encounters or adult gigs section? Would cops be allowed to lure you in that way?
Interesting question. It depends on whether the Internet is considered a public forum or not. I'm guessing as long as you're not too obvious that you are asking for sex in exchange for money, you would be ok. That's probably why some girls say the money is only for companionship... two consenting adults... blah blah blah.
I highly doubt cops could lure pooners that way, because if it is illegal to post an ad soliciting sex for money, then the cops would be committing an illegal act themselves to catch a criminal, which is a legal no-no.
