Airport/Security Checks, Manila
There are all kind of risks in Manila. From kidnapping, armed robbery, pickpocketing, drugged drinks. My hotel , the most luxurious one in Manila, had metal detector door to go through and everyone entering the hotel was frisked, bags searched. That should give you an idea.
Be aware that if you are planning to carry a weapon in Manila, for some strange reason many establishments (and especially the airport) will not let you in! ;)
