At 5:30AM as I was about to exit my suite and into the lobby, I notice 2 unkempt looking males that were loitering about sitting and sleeping there. And they reeked of body odor too. After I locked my door, I glanced at them from a reasonable distance (didn't have my CC pistol with me since I im in the Navy and work on base and carrying guns there is Federal offense and a career ender/ only personal defense weapons I have and is legally allowed to carry are my Spyderco Endura IV tactical knife and Surefire 6P Defender tactical light) as I walked by. Didn't talk to, confront them or stared at them menacingly but I did use some eye contact to make them know I noticed them. As I went to my car and parked in a different parking lot, I called the dispatcher for the VA Beach Police and gave him the information on the suspicious guys as well as their exact location. Also had him tell the officer to check the front door afterwards for any forced entry. Then I left the message at the leasing office of my apartment and told them what is going on and told them to get their security guard or mantenance man to check the area where those guys were loitering and also had him again check the front door of my suite for any forced entry. I also gave the dispatch/landlord my phone number in case they have to notify me that a forced entry occured at my residence. Last I heard that the guys loitering over there were field interviewed and given a warning not to come back or risk getting arrested. I am going to let my other adjacent neighbors know about them when I see them after I arrive home from work.
