Does anyone know if this is an Assassin bug?

So I thought this looked like an assassin bug, but I am not really sure...Do you know?

I hope so cause I released it...into the garden!

We finished this bed. This is a different angle. Also has a little Patch Master around it! Hopefully I can get the baby bunny to stop eating the marigolds long enough to get them to grow to more than just stubs! I put some blood meal out yesterday, hope it helps.
