After evading or destroying (if possible), move towards the middle of Central Park. Having a military disguise helps avoid the fight and chaos. But if you intend to be destructive, go ahead and start killing the soldiers for a missile launcher. Grab one and fire at the marked APC. The target should come outside of the tank, sprint towards the target and grab him. Consume your target, watch the memory and escape the scene as the soldiers aren't happy to see you. Alternatively if you still have a military disguise, transform and walk close to the APC. You should get an option to sound an "all clear". And when activated, your target walks out of his protection. Sprint, grab and consume him, then evade the military.
