I'm no fan of PP. However, they are NOT enticing folks in for an abortion, as the article seems to imply. They seem to be trying to get them to come in use their "community" services for counseling on birth control & safe sex.
I'm not certain why they seem to care so much about building "floor traffic". I admit, it's gross if they are trying build relationships with young people if they only want to perform abortions, however I suspect the reality is more complex.
The reality is that they're trying to familiarize large numbers of teenagers with the availability of contraceptives and STD screening. By luring a few dozen in with an iPod giveaway, they start conversations in the girls' social circles "Hey, see my new iPod!", "Cool, where'd you get it? How much was it?". Next thing you know, lots more girls than got iPods know where they can get contraceptives, and don't feel intimidated by the place, and probably have more specific and accurate information about contraceptive options thant hey had before. Looks a bit sleazy on the surface, but I expect it's being used in neighborhoods where nothing less sleazy would have much impact.
My guess is that the management of Planned Parenthood is paid quite well.
