I just reported two Israeli-looking men in a newish, dark blue Infiniti car after they parked across a school district building and took pictures of the building. The building's parking lot is empty because the venue is closed but the men parked in a different lot across the street and down a little way. One man got out of the car and walked up a grassy area be positioned in front of the building. He remained across the street and took pictures. The incident lasted only a few minutes. I was standing about a block away and they didn't see me see them. As soon as the man got back in his car and it started to drive off, I walked loser to the road hoping they'd come my way. They did and that's when I got their license plate number and make of car. The men were in their 20's to early 30's, clean cut and they looked Israeli. They finally saw me see them and look at their plates. The driver immediately turned into a bank parking lot and stopped at the entrance. It appeared he look out his wind to look at me and it appeared that he took a picture of me, too. Then he drove off. I didn't report the last part about him taking a picture of me because I don't think it's relevant. It's suspicious that they're taking taking pictures of a government building, especially a school building when it's closed, and they seemed to not want their car to be on camera in the school's lot.
Was I reasonable or unreasonable to report them?
