Because Saul reported back what he found when he was checking out the wreckage. Not to mention that all the way back in earlier chapters, they knew the Mallers had access to a couple of tankers.

(Which again, I don't think the tankers were ALWAYS intended on harming the Tower people. I think that they had their own plans before the Tower was even any knowledge to them)
