OK - ignore part of my earlier question...

But I still wonder if it was the occupiers who fitted these or the
council?

As they were tied into the wall, they must have been put up when the
houses were built. *There is flushing along the wall above the joint.

that doesn't follow at ALL.
easy enouh to add flashing and tie into an existing structure.

And what is more, it will actually weaken the wall[1] making it less
able to withstand exactly the kind of force it was going to exert on it.

[1] Raking half of a whole mortar course to insert the edge of the flashing.

Masonry walls stand by gravity so it makes little difference.

It does when you have a car port applying a turning moment to the
wall.

But the fulcrum is outside of that moment. The fulcrum is on the lower
edge of the brackets. So the slot cut is neither here nor there.

In any event no simple masonry can withstand significant tension
forces.
Which is why it fell down. The tensile forces exceeded the
compressive (ie gravity) ones
