This was my thoughts as well. It seems like laying low for a couple of weeks (if you can afford it) would be the easiest way to avoid possible threats. Rent a car and go to another state or something.

If we have to go all "Jason Bourne" on it, renting a car would probably make it harder for people to track where you are going, should they have access to flight-transfer systems etc.

>what risk do you take by going on a vacation for a few weeks?

But what about afterwards? Assuming this to be true, you just return to normal life after a few weeks?
