Thoughts on homegrown militia?

[I-K-E]

The black death did have global transport, motorways, trains and planes and people didn't travel any major distance to work

I have wondered what something like the black death i.e. killer disease with no known cure would do in todays modern global society. Just thinking say if me and the OH where carriers just look at the jobs we do and where we work we could infect a minimum of 3 towns/cities and potentially many more if such a thing happened
