Robert Lieblich: (comment to "There's guns")
"There's" is quite commonly used in speech and informal writing as if
plural. See, for example

Over the years there have been several threads in this very NG about
using "there's" as if plural. Some people think it's an error, and
some don't.  What cannot be denied is the frequency of the use -- it's
quite common.  I see nothing wrong with it in casual speech and
writing, but that's just one person's opinion.
