She then asked if she could enter my home to "look to see what kind of carpet" I had. I (stupidly) allowed her to come in.
Unless you were actually interested in the service, yeah, stupid move. Even if she is legit, now you have to get her out to go about your business.
She followed me to my living room and started making small talk, such as "When was the last time you have your carpet cleaned? Is there a lady of the house I could talk to? Is there anyone else home?" I advised that I only vacuum and I only live with a room mate.
Do not volunteer information about your living arrangements to strangers. And if they ask, LIE.
Example: "we're going to be back in the neighborhood tomorrow afternoon to drop off this free sample of (insert product). Will you be home to accept, or should we just leave it somewhere?" Your answer: "Yeah, someone is
ALWAYS home" In my case, that would be a true statement, but I still said that when I
did work away from home.
She then asked for the can of Febreeze back, because it was "the only one she had" at the moment and that she would return later than evening around 6:30pm to have people shampoo our carpet.................. She never showed up, nor did anyone else at 6:30pm.
If she was legit (and I'm thinking pretty good chance she was based on the info you've provided), she probably deduced that you were not a good prospect.
I think she may have noticed my gun in my waistband printing a little bit, and seemed a bit frantic to exit my house.
Some people are just that scared of guns.
This afternoon, I left my house to do some errands. As I'm leaving the neighborhood, I notice a red Ford Focus parked near the entrance to the neighborhood with an African American gentleman sitting in it just looking around. I double back around the other side of the neighborhood so I can end up behind the car, pull up behind the car and write down the tag number. At time, the car starts up and he drives away.
Though others have jumped on you for the racial comment, fact is, profiling is a useful tool. If a person's race (or vehicle, manner of dress, etc) is out of place in your area
and their behavior could be perceived as nefarious, you have good reason to pay closer attention to them. He may well have just been talking or looking something up on his phone, but if that was the case, there is no harm in what you did. You did not accost him; You simply took notice of him. If he
was up to no good, being noticed probably did scare him off, and that's a good thing. Either way, you did nothing wrong.
As an aside: Overt surveillance cameras are a very useful deterrent during the probe. Even if the person probing won't be the criminal actor, they are an associate, and they know darn well that they'll be a person of interest in an investigation following a crime. The systems are cheap these days, and well worth having, IMO.
