It is not up to us to judge on this particular incident, although it is worthwhile noting that several leading BNP members - including leader Nick Griffin - have convictions for incitement to racial hatred and violent attacks on members of ethnic minorities.
Regardless of who is right or wrong, the BNP have taken it upon themselves to traduce Ms Tobin and undermine her reputation. One BNP-associated blog, Made in Yorkshire, was deleted by Google-owned Blogger after it published Ms Tobin's address and sent her a "warning" - a development that has led to another police investigation.
The neo-Nazi forum Stormfront has also seen some ugly bullying of Ms Tobin, a nurse and a mother of two who says she is now too afraid to leave her home. Here are a selection of the comments left by extremist BNP supporters:
"Canvasser didn't wan't it back after the ape had touched it. Never know where it's hands have been. yuck"
"I bet she's a subsidy monkey. Let's hope the rest of her tribe also become agraphobic, and stay indoors, and off the streets."
"They are nasty mongrels and deserve what they get."
The BNP have started a letter-writing campaign to local newspaper editor Dominic Yeatman, calling on him to "desist from printing the deranged rantings of bigoted ethnic-minorities ever again." In one BNP-supporting blog, there is mention of a campaign to get her sacked from her job as a nurse. She has also been referred to as "The Screamer" and BNP supporters have claimed that she is "large" so therefore couldn't be a victim of racist abuse by the supposedly "elderly" BNP activists.
Whatever happened in relation to Ms Tobin's altercation with the BNP, the far-right wants to punish her. It seeks to intimidate her and her family and traduce her to the extent that she would not be able to work. All this is despite the fact that the BNP activist at the centre of the controversy has never been identified, so has not suffered as a result.
