No it is not still within the laws of cricket since the late 1930s.

You might notice the law changes section in that article, that amongst other things you can't have loads of fielders behind square on leg side now.

I would also suggest it is not considered unsportsmanlike to bowl short and aim for the head any more, but rather something people look foster's forward to seeing.

I was about to post the same thing when I noticed this comment.

For those who might not want to go through the article:

> ...designed to combat the extraordinary batting skill of Australia's leading batsman, Don Bradman... aimed at the body of the batsman in the expectation that when he defended himself with his bat, a resulting deflection could be caught by one of several fielders deliberately placed nearby on the leg side. At the time, no helmets or other upper-body protective gear was worn, and critics of the tactic considered it intimidating, and physically threatening in a game traditionally supposed to uphold conventions of sportsmanship.
