Definately, because of the multi-faceted nature of this conflict. Some tango, somewhere, will go, "You know, lets kill some cops today." And another one will go, "Why?" And the first one will go, "Because it'll make the papers."
I looked at the 9/11 attacks, and when the second plane hit the second tower, I initially thought, "That's wonderful. They waited long enough for EMS to arrive and get tied up, then brought the other building down on their heads." Ie: They diliberately attacked again, to destroy or hinder the effectiveness of NYFD and NYPD. With the insanity that was going on, and the reduction of manpower, another attack somewhere else in NYC would of been even more effective. As it turned out, these were highly devistating symbolic attacks on their own right, and no further targets in NYC were selected that day.
I could see people targeting EMS services, say, the county ambulance headquarters, a hospital, the local fire department. After they're all tied up dealing with the damage caused to the infrastructure, a chem/bio weapon could be deployed at a shopping mall, stadium, or downtown Anyville, USA during lunch hour, when everybody's out and about walking to the local deli. They'll hear about the ambulance HQ being hit, and go, "That's too bad." The hospital may give them pause, but ya gotta eat.
In such, hitting targets before a planned strike to hinder response sounds like a good tactic, and something I somewhat expect in the future.
In another vein, release a suspect chemical agent in a shopping mall (OC would be effective), etc, and when the police and fire department show up, blow the place up. Your targeting the population center, and the responding EMS force and responding police.
If your in the homeland security, law enforcement, or private security professions, I suggest you sit down with your fellow officers, get some maps or use Google Earth, and plan out how to successfully attack and destroy your own area of operation/jurisdiction/client(s). First, do it using public knowledge, ie: the internet. Then, do it using your personal knowledge, including tactics, doctrine, and emergency response plans.
When you have the attack plan made up, gut it, and figure out ways to defeat it at each step. Then do it again, with another scenerio. I'm sure there are people in your organization who have a novel way of crippling it.
