No evidence of asymptomatic transmission

Simon Dolan needs to see this as this destroys the case for lockdown. One of the justifications used for draconian lockdowns is that healthy asymptomatic people can spread the disease which is why lockdown laws must apply to everyone. As can be seen from the response the government can't provide any evidence asymptomatic transmission exist. Can this be used in legal action against the government.

Could the following questions be answered :- * Has any research been carried out by the government into asymptomatic transmission. * If research has been carried out into asymptomatic transmission, can the following be answered How do asymptomatic carriers spread the disease as unlike symptomatic carriers they will not cough or sneeze. How long do asymptomatic carriers stay infectious. Are asymptomatic less or just as infectious as symptomatic carriers. * Have there been documented instances of people who tested positive but had no symptoms and those around them fell I’ll. * Is the possibility of healthy asymptomatic people spreading coronavirus a major factor in placing draconian lockdown laws on the entire healthy population. * If there is no evidence of asymptomatic transmission, would the government still feel draconian lockdowns which apply to whole population would be justified.” NHS England does not hold information in relation to your request."
