Abstract: Abstract Winful objects to our appeal1 to pulse reshaping discussed in refs 2,3. It is these discussions, however, that show that causality is maintained in the tunnelling process and that no fundamental tenet of modern physics is called into question. Although these discussions were put forth for short pulses, they are not, in principle, limited to this case. Indeed, pulse reshaping also occurs for long pulses, even if only at the leading edge of the pulse.
