Why police officers defending me when people made stupid 911 calls?

At parking lot one of big supermarket, I was waiting on friend who work at supermarket. Friend supposed get off on time but didn't, keep working overtime by half hour.

While I was waiting, I got bored, so I decided to dance like doing rocks, I bounce on my own vehicle. I'm just having fun and being goofing off. Some other nearby at parking lot called police on me.

Police showed up, police asked what I am doing. I explained was waiting. I told police I'm just doing jumping on my own vehicle. Then police ask did you do any sexual dance or humping on objects or on vehicle, I say no, police say ok you're good to go.

Next morning I reading online police every 911 calls reports.

It said my vehicle where I am located. Caller complains I doing sexually dancing and trying to have sex with my own vehicle. Officer stated online I was doing jogging and some exercise while waiting on somebody. It's all clear.
