We had our apartments burgled, there were four apartments in the area. Guy kicked down the door, and apparently was in an out pretty quickly.
I came home from work, cop told me, never leave valuables in your nightstand. Might have even said bottom drawer. Sure enough, mine were checked, I could tell because my envelopes were moved from where I placed them.
If it's empty, you can cut a hole in the bottom, for example, clean the inside and make some type of lid, to close it again. It's not like anybody will be inspecting it in detail ;)
