An apearent uptick in brandishing along I95 in the Philadelphia area is the inspiration for this one. Actually all highways in that area (76, 422, 676, 1, 202,etc.) are noted for unfriendlys. What would it be like to have an armed engaugment @ 60 mph? If you "prevailed", even if you can prove self defense, & the other guy crashes & causes a death, are you liable for manslaughter? Of course you disengauge to the best of your ability, but when you are pulling a laden trailer, you have much less ability to manuver then your assailant. What would be the rammifications of taking defensive action here? Other options besides risking bullets in the on comming lane are prefered. Thank you for your serious consideration.
