Shocking turn of events

About a year ago, at the apartment building I rent out, I was showing the apartment to a man about my age, who was interested in the apartments.  I turned around to see him pointing a gun at my face.  Nothing I had was worth my life, and wanting to go home to see my toddler son and pregnant wife, I gave him my wallet, new iphone, and everything else I had.  He took off with no incident.  A week later, the same guy, armed with my info, tried to break into my house.  Luckily I have an alarm.

Now today, I get a call from one of my tenants, that a man walking in the alley right behind my building was held up by two men, whom after getting what they wanted, shot the man and killed him.  The two men that did it meet the description of the guy who robbed me, and his set up man (who had inquired about my apartment about 30 minutes before I showed it to the guy who held me up).

It's quite sobering to see that the man who held me up, and his buddy, were/are willing to kill.  That could have easily been me that was killed.  Yet, as a landlord in WI, I cannot carry a concealed weapon with me.  Police and other "officials" are always talking about statistics, and how, statistically, once they get what they want, they won't hurt you, they'll just flee the scene.  Right, just like they'll leave me alone after robbing me, and won't try to break into my home.

I guess it's time to sell the investment.
