Hung vs. Hanged

[Vishnya]

Hi,
I made test in English and faced the challenge. Can you explain something to me?

The sentence was:
Since the abolition of capital punishment in this country murderers are not hung if they are found guilty.

I should find any mistake in this sentence and I found it. The mistake was hung.

I correct the sentense and it became like that:
Since the abolition of capital punishment in this country murderers are not hang if they are found guilty.

But! the answer was like that:
Since the abolition of capital punishment in this country murderers are not hanged if they are found guilty.

I understand that my answer was incorrect but the verb to hang is an irregular verb, isn't it? And it hasn't such form as hanged.

Although many people now use 'hung' for capital punishment, some grammarians still like the distinction between the two verbs:

hang / hung / hung (for clothes in your closet, etc)
hang / hanged /hanged (for capital punishment, suicide, etc)
.
