According to the Bureau of Civil Aviation Society( BCAS), there is high probability of differently-able person carrying weapons and explosive, therefore there is ample reason to be alert.
The Disabled Rights Group (DRG) has described the regulations as “disability insensitive and outright insult and violation of the human rights of persons with disability.”
“What is even more shameful and embarrassing is that countries that have a greater security threat and stricter security programs have defined guidelines for screening passengers with disability. At no airport in the U.S., the U.K., the European Union and even countries like South Africa, Malaysia, Hong Kong, Korea, Thailand, and UAE will a disabled passenger using a wheelchair be asked to ‘get up' from her/his wheelchair,” Mr. Abidi said.
