Advice on crime prevention

I have heard of the following:

1. Leave your lights on - a) this will deter burglars since they will think some one is home, but b) won’t they also be able to see directly that no one is home? or provide the light they need to break into the house?
2. Don’t plant shrubs near your windows or doors - a) this will provide hiding places for them, but b) won’t this also prevent them from getting too close to the windows and doors?
3. Get steel doors and have good locks - err but can’t they just bust a window like they did to us?

If I had a choice of what to live in, it would be an earthship, with commercial grade glass - the ones used for office buildings - for doors and windows.
