Do Cops/Rad Vultures Try To Shoot Out Windows?

[Vaeliorin]

Presumably, zombies are able to see you through the new window options in the shape menu for building blocks.  Given that a single hit is enough to break the glass, at which point it can be shot through, do zombie cops/rad vultures spit at the glass to try and break it so they can shoot you, or will they ignore it as long as it remains unbroken?

 

Just curious if I can use them in a horde base to allow me to see out without giving the zombies extra vectors of attack.
