That may be the "literal" reason they are there sure but I think there is a reason beyond the most obvious one. The mention of the Suicide Squad plus the Outlaws going to a Colony base in the solicit for issue #17 alone and the Colony being a group the 'Tec team has fought before makes me think there is a bit more to it than just Batwoman locking up the Outlaws with the Suicide Squad and throwing away the key.
