This type of caution is typically practiced by institutions and larger private sector organisations seeking to minimise exposure to personal injury or similar legal claims but has during the early part of 2020 increasingly been adopted by individuals seeking to cover up their total panic on realising their previous publicly stated position on a matter of significant risk was riddled with hubris and incoherent bravado.
