'You don't feel safe': raid resident

After two counter-terrorism raids in the same Sydney street in just 12 months, Guildford resident Bruce Crook doesn't "feel safe" anymore.

The usually calm Bursill Street was thrust back into the spotlight following pre-dawn raids on Wednesday.

Across the road from the raided house, the home of Omarjan Azari who was allegedly directed to behead a random member of the public last year, is the Guildford Bowling Club.

The quiet venue is frequented by elderly patrons and pokies players - a stark contrast to the heavy police presence on Wednesday.

"You don't feel safe," said Mr Crook, a member of the club who lives nearby.

"What are they being taught? What's getting into their brains?"

The Guildford raid was part of a series of police operations across five locations in western Sydney in relation to the fatal shooting of a police accountant outside Parramatta Police Headquarters by a teen gunman last Friday.

"What made a 15-year-old - he hadn't even started his life - do that so dramatically? Who put the gun in his hand?" Mr Crook said.

"They're all just sitting back and letting everything happen.

"How did that happen? Wasn't that kid talking to someone?"

In Marsfield, residents were also shocked and confused.

Georgia Teirney, who lives across the road from a house raided on Booth Street, said it was a confronting scene to witness on Wednesday morning.

"The people with the guns and the masks, being in your street, not knowing what's going on, not knowing they're cops," she said.

"The cops have always done drive-bys every now and then, so we thought something might be up.

"So when that happened, we knew it'd be something to do with Parramatta.

"They're nice people but I think they're just mixed up in the wrong crowd."
