Had I not possessed cameras, what were the odds I would've been able to see the driver's face and/or license plate given how fast he overtook me? If by some miracle my eyes were able to see both AND the cop was willing to investigate based on my sole eyewitness testimony, the registered owner would've simply denied wrongdoing. That would have been the end of that. Instead, the cop was able to bring up the YouTube video on his phone and show it directly to the driver. At which point the guy couldn't deny it, so he tried to play ignorant by saying he was unaware of the KS 3-foot passing law.
