No, cards are placed in discard pile immediately, even if they have an efffect on subsequent rounds (like Red Scare), unless they are underlined. Only the underlined cards are kept out, by the side of the board, as per 7.3.Check the consimworld post linked above - it deals with the situation where Red Scare occurs more than once in the same turn, because it is recovered from the discards via an event and played again. That would be impossible unless the Red Scare card is placed in the discards immediately.
