I was flying my drone from my own property, when as I landed five cops showed up to ask if I was flying. I said yes . They then asked to look at the drone if I would go get it. I did . I gave the drone but held the remote from them, they then as holding my drone started telling me how I was breaking the law. They stated under rule 107 I was flying at night ,and over people. I then told them I flew under a hobbyist rule not 107 rule. I gave them my paperwork and they couldn't say anything. They told me call the station in 5 days and I can get a police report, took my drone and left without fair reason .week past got report it had I criminal trespassed on it. AS of yesterday a month later , I was called to come get my drone from them. Along with the drone I was given a copy of a search warrant that was written the day after for my memory card etc. I was told they now were not gonna charge me for trespassing they needed some crime reason to get a warrant. Has this ever happened to you,? What are your thoughts?
