But it is not proper to engage in a general attack on the character of the witness. Pandula v. Fonseca, 145 Fla. 395, 199 So. 358 (1940); Taylor v. State, 139 Fla. 542, 190 So. 69 (1939); Nelson v. State, 99 Fla. 1032, 128 So. 1 (1930). While the defense had the right to question Capo as to the whole of the conversation he spoke of on direct examination, Louette v. State; Haager v. State, and as to the factual background of the conversation, to question him generally about his role in the marijuana smuggling operation would have been to engage in a general attack on his character.
