Should I be worried to go to Chattanooga?

I've been one other time on a two day trip and
had a great time. No problems at all, we stayed
in downtown Chattanooga. Since then I've
heard of two small scale mass shootings and
was looking at how safe the city is, it definitely
is not the safest. It's me and my friend, two
young 20 girls. We'll have a taser and pepper
spray (I'm getting a gun soon but not in time
for this trip) we're staying at a koa
campground near lookout mountain and other
than a grocery store near it, that's the only
place we plan to go In Chattanooga.
