If somebody has a problem and was following me, and I thought they intended to do physical harm upon my person...I'd call a friend, let them know where I am and I might need their help, put them on speaker phone...and then confront the person calmly, all the while palming a weapon. I'm a firm believer that most people are inherently decent human beings, and most situations can be resolved without resorting to violence.
If, however, it goes poorly, the guy's going missing. Put him in the trunk, call a friend, tell him to bring a circular saw, and some black trash bags.
Take him to someplace with a shower, hang him by the ankles and slash the throat all the way back, so that most of the blood will come out at once. For the rest, work the arms like pumps.
Take a smoke break. Throw on some classical music or some vintage madonna (the newer shit sucks), or some aqua or venga boys...
Go back into the bathroom, start working on the limbs, disassembling them at the joints, cutting away sinew like tendons and ligaments...and then gift wrapping them in the plastic bags after spraying the pieces down with mace or pepper spray. Carve off the finger tips, and break the teeth with a hammer. To make identifying the body a little more difficult.
Then start dropping the bags off in dumpsters all around town, or burying them in different remote locations, far enough off any hiking trails and deep enough that animals won't try to dig them up...the mace or pepper spray should also help throw the scent.
...
thank the rap music and CSI. jesus.
that was sick...I'm sorry.
