Every barrier can be defeated, the question is how much work someone has to do to beat it. Over time the mortor breaks down and the block is hollow.
Now cover that block wall with wire mesh and stucco and it becomes more difficult to penetrate. Steel rebar inside the block, what's behind the block wall (interior finish). But a lot of older buildings it's just the block, and tht can be cracked withuot to much effort - hammer and chisel, sledge hammer
It could be sheathed with 1/4" A-36 steel plate too. Or titanium....ballistic Kevlar.....all three...
I'm pretty sure Ken was looking at those block walls and musing: "Ya know..I bet somebody is going to bust a hole right through that soon. I oughta spend a lot of money to armor the building."
That's what I would have done.
