It looks like in both cases they were pulled over for speeding. Other things they may pull you over for are lights and loose items on your vehicle; such as bikes tied to the ladder that the officer thinks may fall off, or muffler bracket broken with the muffler hanging down.
It is necessary for those of us that recognize a need to keep our family safe, to write our representatives in support of a national concealed carry permit. Especially for those that spend a majority of their time on the road. Such as salesman, RV'rs, and truck drivers. There have been a number of truck drivers killed parking near a shipper or receiver. I've not heard of many RV'rs robbed and shot, one would think they carry more cash than truck drivers, so I believe this is a lesson as to where to park. Industrial areas are not as safe as most other areas. Rest Areas on the highway have seen many shot and killed though, that's why many states are either shutting them down or providing security. But we should be able to afford ourselves to the choice to either carry to protect ourselves, or be content to rely on the cops to draw a good chalk line around us and each of our family members.
PLEASE, take the time, write and call your representatives. Make sure they know you support, and expect them to support, a national concealed carry license to end this madness.
