Rubs and scratches are more likely but I changed my mind a lot when someone in 
my studio knocked my Canon 5D off a stool a few years ago. It landed LCD first 
on to a tripod dolly. It was wearing a Giottos glass protector rather than a 
thin film protector. After the perpetrator recovered consciousness and I'd 
changed my underpants, I peeled the shattered remains of the thin glass off the 
screen to discover - no damage at all underneath. Consequently, it was wearing 
a fresh screen within 2 days and every expensive camera I buy gets that present 
quite soon in life.
Now, those screen are a LOT closer to the LCD screen than a filter is to a lens 
front element. But I'm betting that a glass fracture absorbs a lot of energy. A 
point impact that could penetrate a filter and mark a front element or drive 
filter glass fragments into it would possibly destroy that front element 
completely if no filter was in place. And a marked/scratched front element 
isn't that serious - it'll give perfectly acceptable images until you can get 
it fixed.
