How do you know she 's not going to go rifling through your drawers for dirt ?
你怎么知道她不会暗中查你的毛病?
Modern bullets gain their accuracy from a technique known as rifling , whereby the barrel of the gun that fires them has a series of spiralling grooves etched into it . These cause the bullets to spin , and that spins stabilises their flight path .
Some social media users , for example , questioned whether police were handling evidence properly after a photo was published showing an unidentified man rifling through zhou 's belongings without wearing gloves .
