Arms went astray for those lacking integrity (5,3)

I believe the answer is:

straw men

I'm a little stuck... Click here to teach me more about this clue!

'those lacking integrity' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'arms went astray' is the wordplay.
'astray' is an anagram indicator.
'arms'+'went'='armswent'
'armswent' is an anagram of 'STRAW MEN'.

'for' is the link.

Can you help me to learn more?
