Certainly a possibility, though Paris was also the location of the Charlie Hebdo attack. Given that this attack was successful — getting out alive wasn’t part of this op — Paris proved to be a vulnerable target even given the recent Charlie Hebdo murders. The “unhit” targets would give insight into other potential types of targets by the Muslims.
Seems to me that getting captured was not an option for them but some of the killers may have escaped and be on the loose.
