Singh [literally "Lion"] is a marker for Sikh.
Sikhs wear five visual sign of their dedication to their faith:
Wear the Sikh undergarment for modesty and healthCarrying a knife at all times is an article of faith...
Wear a wooden comb in the turban to keep hair clean and untangled
Wear a steel wristlet as a sign of faith
Wear hair uncut, to honor the creator’s intention
Wear a small sword symbolic of defending the religious rights of all faiths
Aren’t Sikhs normally peaceful, but they’re vicious fighters if provoked?
Many Sikhs have a sword engraved into the handles of their combs to carry out the sword requirement.
Sikhs are, in principle, the opposite of violent. Those who serve in the military are medics, pharmacists, etc., never in combat roles , because of their religious principles. Their “blue turbans” who serve in UN missions as pharmacists and medics are well known and loved for their kindness and generosity to local people and refugees. The Sikhs I have known are kind and generous to a fault. I knew one former Sikh, a highly intelligent and personable man, the chief electoral officer of India’s largest electoral district, who had decided he could not put with the long hair, comb, bracelet, etc., stuff any longer and shaved his head(!). But he still believed in the Sikh principles.
Sikh ahimsa (usually translated as “non-violence” but not an adequate translation):

The Sikh who stabbed that poor Canadian man did not do it because he was a Sikh, but in spite of it. Mental illness seems likely.
They cherish their women and allow them to be pretty. Sikhs have a large representation in the population of Northern California. They are not usually involved in crimes and they are almost never terrorists.
Yes, but it didn't look like he was wearing a turban when police got him, so I wonder how religious he was.
Sikhs may be gentle and non-violent in principle, but if she could, Indira Gandhi would tell us that that isn't always carried out in practice.
