space...

mirrors are made of aluminum anyway

Vampires cant reflect off of pure metals like silver

Mirrors then were silver. We use aluminum now

There could be vampires anyway these days

That's not how it works.

Traditionally, vampires don't show up in mirrors.

Anywhere* these days

Space... the final frontier.

Unless you're undead. Then it's only the penultimate frontier.

If zombies are only half-dead could someone press murder charges against you if you kill(?) One?

If they're only half-dead, you might need to kill two.

Maybe you'll get ½ degree murder charges for one

Different countries have very different "rules" on how to kill a vampire.

The old "wooden stake through the heart" trick is a European invention. 

On the plus side, it works on normal people too; so if you have any stakes left over, you don't have to waste them.
