Some people just overreact, a person at a job a relative works for has an employee that complains about people looking at her (not sexually), just looking at her, shes filed at least 8 or so of these complaints to HR.
I was gonna comment about the scared following and her circling him but Patriot already hit the nail on the head.
however I do hope they get on her about filing a false police report, or at least inaccurate report. Just something to put the light back on her and make her think twice about causing issues where theres no issues. I could see if she had been simply walking to her car and saw him with a gun and called it in as a concerned citizen.
