BSA's Sec 4: The Hodgepodge of Oral Evidence

Ab kya hai yaar, main toh phir se padhne gaya, aur fir bhi confusion hai. Ye Section 4 mein kya likha hai ke aapko oral evidence ki proof aur oral evidence ki recording dono hi zaroorat hai, toh kya aapko evidence record karni hi padegi ya phir mere pas record nahi hoga aur court mein bolna padega, aur phir kya court kya kahega? Aur fir, yeh baat hai ke oral evidence ke case mein court ko mere baat par itni conviction nahi hoga ki aapko saabqati mile, toh kya aapko evidence record karni hi zaroorat hai, or yeh bata ke court ko mere baat par itni conviction ho jaaye? Yaar koi batao.
