The Coluans not wanting us there on Talok IV at all would've made for a bad trap.

But wanting us there like the Naltorians and Carggites did, as just guests, where we couldn't control security, but would feel the need to act if something bad happened? That was a perfect setup.

Plus Cargg also wanted less security on their own planet and wanted it right before the Joker's attack? I could see other planets voting for less security for some stupid reason, but you'd think the Carggites would've fought against that.
