Energy Minister Amber-Jade Sanderson, visibly shaken after the incident at colleague Hannah Beazley's office, said being a politician has become more risky. "It is becoming more and more challenging to do this job," she said. "I love being an accessible member of Parliament, but I've certainly noticed over the last two years in particular it's getting harder and harder to do that."
Police officer-turned-Labor backbencher Mark Folkard, who said he is dealing with a stalker, questioned the drivers of the tension. "Everyone's saying let's take the heat down, but what's the driver of the heat? That's the question we've got to be asking," he said.
First-term Liberal MP Adam Hort described the week as "a dark week for democracy in Australia" and said it is "awful" that MPs have to second-guess being available for their community.
Opposition Leader Angus Taylor pointed to a loss of trust in institutions, saying that gets worse if MPs cannot engage with people daily. WA Deputy Premier Rita Saffioti noted policy debates have become more "extreme" and that people are "dehumanising politicians."
Government minister John Carey, who is often a target of abuse due to his housing portfolio and because he is openly gay, said dehumanisation on social media creates an environment that enables violence against anyone in the public sphere.
One Nation's WA leader Rod Caddies, who said he was threatened while driving home the day after Dr Haines was attacked, urged caution about security measures. "[It's] just treating a symptom of a problem that's there. We need to always be looking to treat a cause and not the symptom," he said.
Police Commissioner Col Blanch said the threats in Western Australia are not as great as elsewhere, but acknowledged the anxiety politicians feel after an attack. He advised MPs on how to look after themselves and what to look out for.
The state government has announced funding for security upgrades at MPs' personal homes, a fast-tracked security review of Parliament, and an additional electorate officer for each MP.
