Getting a full or partial print of any sort can be useful. Latent or otherwise. If you have prints from a boot/shoe then it is possible to identify the brand and make from the sole pattern.
From the print it is also possible to obtain a detailed summary of the little twat that did this. As each individual will walk and wear shoes slightly differently. (Wear of the sole). With this detail(S) in mind it is possible to determine a persons gait and potentially ID an individual, however, it all coems down to the print, who works on the case and interprets the information available to them. Unfortunately sickening as it is the people (Volume SOCO's) will not go into the lengths and time consuming investigation to catch them unless its an obvious case to deal with.
My car got a BBQ thrown onto it and smashed the bonnet up on my leon. But unfortunately the Volume SOCO's were unable to do anything.
Hope you get the car sorted and the little twats get caught!
