Not letting shady people in your house is common sense.
Aren't you the one who got robbed of you're video game collection? I recall reading a post about it awhile back.
If anything whether it was a stranger or linked to someone you knew, point is you should get where I'm coming from considering you had your games stolen.
statistically speaking I'm pretty sure there is a high % of robberies where the victims are associated with the perpetrator more so then a random robbery from a stranger.
Normally they know what they came for and they know what they are looking for. To what % these statistics are fact I'm not sure but I know it's not the first time hearing it.
