I'm always careful, keep valuables out of sight, etc., but I'm becoming worried it's not enough. Another site listed many instances of pretty violent attacks. I feel like I can protect against pickpockets, but not a group of attackers. Is this threat as serious as it sounds? Also, our camera (on strap) is not an inconspicuous one; should we not carry it? I'd hate to not use it but afraid to be targeted. Thanks.
