"On face value, the Victorian government’s decision to construct bollards to prevent vehicle attacks in Melbourne makes perfect sense. Nevertheless, it’s not clear that there is any strategic logic to their deployment. Arguably, the erection of cement bollards in places like Melbourne’s Federation Square will only send would-be attackers elsewhere: and block first responder vehicles during an emergency. The return on investment from these measures, in terms of security, is arguably low. Moreover, this money could perhaps be better spent on intelligence, investigation and early intervention counter-terrorism strategies."
