I agree Joe. But the cost might be the deal-breaker. I think the wall would be knocked over by the first disgruntled nut case that hates cops. Unless crash barriers were set. Like I saw recently placed in front of Northern Station. I was there last night for Police/Community Meeting. Massive posts!
The shear size of the wall will eventually blot out headquarters. Bricks on the ground would be better, cheaper. I pondered a section set aside for “gold bricks”. I think some may have fit that mold. Bricks on the ground in my opinion, the way to go. Pour the concrete pad….I’ll teach you all how to lay bricks. Bring knee pads. We’ll help each other get up.
