Common sense lacking in Florida neighborhood

I try so hard to not fault women for things when they happen to them. I'm a violent opponent to the "she asked for it," thought process that some people spew. I hate that a woman's job, history, sobriety, or intelligence is brought into evidence as a reason why something happened to them. I'm the last person to believe that it wasn't the way she says it was.
That being said: "A 76-year-old man claiming to be a doctor went door-to-door in a Florida neighborhood offering free breast exams, and was charged with sexually assaulting two women who accepted the offer, police said on Thursday." (Italics added by me.)
WHO, WHO, WHO says to a white-haired guy with no credentials that shows up on your doorstep, "Sure, come on in and feel me up. This is a GREAT opportunity to have a free breast exam!"
To make this even more appalling, the women were in their 30s; not old, gullible, blue hairs who never get out anymore. The first woman became suspicious after he asked her to take off all her clothes, and began (that means that she actually DID disrobe! Argh!) conducting a genital exam without putting on gloves. Anyway, she called the cops, and the guy took off. The police caught him at another woman's apartment, in the same neighborhood, a little while later.
And contrary to the apparently very official and trustworthy black bag he carried, and his line about working for a local hospital, we come to find out that he's a shuttle driver for an auto dealership.
Ladies, ladies, ladies!! Don't let freaky old men you don't know into your house to touch you! That's creepy!! RED FLAG! RED FLAG! RED FLAG!
